Answer:
The question is not clearly stated, below is the clearly stated question and answer:
A customer wants you to enlarge a photo to 2 3/4 its current height. The photo’s current height is 3 1/4 inches. What should its enlarged height be, in inches?
Answer:
[tex]Enlarged\ height = 8\frac{15}{16}\ inches[/tex]
Step-by-step explanation:
[tex]current\ height\ =\ 3\frac{1}{4} = \frac{13}{4} \\ magnification\ factor = 2\frac{3}{4} = \frac{11}{4} \\Magnification (enlargement)\ =\ (magnification\ factor) \times (current\ height)\\Magnification\ =\ \frac{11}{4} \times \frac{13}{4}\\ Magnification\ =\ \frac{143}{16}[/tex]
Next, we will concert from the improper fraction to a mixed fraction:
when 143 is divided by 16, there will be 8 whole numbers and a remainder of 15, hence, the mixed fraction is:
[tex]\frac{143}{16} = 8\frac{15}{16}[/tex] (Alternatively, a scientific calculator can be used)
Therefore, enlarged height [tex]= 8\frac{15}{16}\ inches[/tex]
6x + 2 = 9x - 4 help me please
Answer:
x=2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
6x + 2 = 9x - 4
We want terms with x on the left side and numbers on the right side.
Subtract 9x from both sides.
6x - 9x + 2 = 9x - 9x - 4
-3x + 2 = -4
Subtract 2 from both sides.
-3x + 2 - 2 = -4 - 2
-3x = -6
Divide both sides by -3.
-3x/(-3) = -6/(-3)
x = 2

(I WILL MARK AS BRAINLIEST PLS OPEN I RLLY NEED TO KNO PLSSS) a hot air balloon is 10 meters above the ground and rising at a rate of 15 meters per minute. another balloon is 150 meters above the ground and descending at a rate of 20 meters per minute. when will the two balloons meet? i really need to know im super confused and also use the either the substitution method or the elimination method to solve this word problem PLSSSSSSSSSSSSSSSSSSSSS
Answer:
After 4 minutes
Step-by-step explanation:
Balloon 1
Initial position = 10 mRise rate = 15 m/minBalloon 2
Initial position = 150 mDrop rate = 20 m/minTime required for the balloons to meet = x
After x minutes the first balloon will be at position:
10 + 15xAnd the second balloon will be at position:
150 - 20xSince they meet after x minutes, their position must be same:
10 + 15x = 150 - 20x15x + 20x = 150 - 1035x = 140x = 140/35x = 4 minutesSo the balloons will meet after 4 minutes

Solve for y. I REALLY NEED HELP ON THIS!! 2(3y+6x)=2(5y-2x)
Answer:
y = 4x
Step-by-step explanation:
2(3y + 6x) = 2(5y - 2x)
Divide both sides by 2.
3y + 6x = 5y - 2x
Subtract 5y from both sides. Add 2x to both sides.
-2y = -8x
Divide both sides by -2.
y = 4x
h(n)=4n+ 4 find h (-3)
Step-by-step explanation:
h(n)=4n+ 4 find h (-3)
h(-3)=4(-3)+4
=-12+4
=--8
Answer: -8
Step-by-step explanation: h(n) = 4n + 4 means that
if we put an n into our function, a 4n + 4 comes out.
So here, we're putting a -3 into our function which means that
a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.
So h(-3) = -8 or the value of the function at -3 equals -8.

2. Miss. Mead pays Miss. Brown $125.00 per week. How much money must Miss. Brown take in for services if Miss. Mead is to realize $50.00 profit on her work? (Conditions on salary are the same as in problem 1)
ODS
a. $275.00 b. $325.00 c. $250.00 d. $300.00
Answer:
d. $300.00
Step-by-step explanation:
Given that a cosmetologist must double her salary before the employer can realize any profit from his/her work, for Miss. Mead to realize $50.00 profit on her work, you would have to determine the amount that doubles the salary of the cosmetologist and add the $50 needed as profit:
Salary= $125*2=$250
$250+$50= $300
According to this, the answer is that for Mead to realize $50.00 profit on her work, Miss. Brown must take $300.

Answer:
Commutative property of multiplication
Step-by-step explanation:
This property states that numbers can be switched around when multiplying and the answer still remains the same
Answer:
C
Step-by-step explanation:
So we have the expression:
[tex]63\cdot 3[/tex]
And Jared rewrote it as:
[tex]3\cdot 63[/tex]
In other words, he just switched the order and the expression remains equivalent.
This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.
So, our answer is C.

18. A shelf holds fewer than 50 cans. If all of the
cans on this shelf were put into stacks of
five cans each, no cans would remain. If the
same cans were put into stacks of three cans
each, one can would remain. What is the
greatest number of cans that could be on
the shelf?
Answer:
40
Step-by-step explanation:
Given that the number of cans are fewer than 50.
Let the number of cans = [tex]x[/tex]
It is given that no cans remain if they are put in the stacks of five cans each.
i.e. number of cans are a multiple of 5.
Let us have a look at the numbers in decreasing order which are multiples of 5 and are lesser than 50.
45, 40, 35, 30, ......
Now, let us check the numbers one by one.
If [tex]x=[/tex] 45,
Now, they are placed on stacks of three each and one can remains.
So, the remainder when [tex]x[/tex] is divided by 3 will be 1.
But when 45 is divided by 3, remainder is 0.
Now, let us check next greatest number, which is 40.
When 40 is divided by 3, the remainder is 1.
Therefore, greater number of cans can be 40.

What is 5+x+11x=11x+11
Answer:
x = 6
Step-by-step explanation:
Solve for x:
11 x + x + 5 = 11 x + 11
Hint: | Add like terms in 11 x + x + 5.
x + 11 x = 12 x:
12 x + 5 = 11 x + 11
Hint: | Move terms with x to the left hand side.
Subtract 11 x from both sides:
(12 x - 11 x) + 5 = (11 x - 11 x) + 11
Hint: | Combine like terms in 12 x - 11 x.
12 x - 11 x = x:
x + 5 = (11 x - 11 x) + 11
Hint: | Look for the difference of two identical terms.
11 x - 11 x = 0:
x + 5 = 11
Hint: | Isolate terms with x to the left hand side.
Subtract 5 from both sides:
x + (5 - 5) = 11 - 5
Hint: | Look for the difference of two identical terms.
5 - 5 = 0:
x = 11 - 5
Hint: | Evaluate 11 - 5.
11 - 5 = 6:
Answer: x = 6
Answer:
x = 6
Step-by-step explanation:
5 + x + 11x = 11x + 11
5 + 12x = 11x + 11
5 + 1x = 11
1x = 6
x = 6

Maggie’s brother is 3 years younger than four times her age the sum of their ages is 27
well i think maggie would be 6
Step-by-step explanation:
6•3=18
18-4=14
14+6=20
Answer:
[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]
Step-by-step explanation:
We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.
[tex]m + b = 27[/tex]
[tex]b = 4m - 3[/tex]
We can now substitute [tex]4m-3[/tex] in as [tex]b[/tex] into [tex]m+b=27[/tex].
[tex]m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6[/tex]
Now that we know the value of [tex]m[/tex], we can substitute it into [tex]m+b=27[/tex].
[tex]6 + b = 27\\\\b = 27-6\\\\b = 21[/tex]
Hope this helped!
Hi Geovannie, when you submit this form,
Required
1. Solve the equation:
-(1+4x)=4(1-x)-5*
(5 Points)
Steps to solve:
-(1 + 4x) = 4(1 - x) - 5
~Distribute both sides
-1 - 4x = 4 - 4x - 5
~Combine like terms on the left side
-1 - 4x = -1 - 4x
~Add 4x to both sides
-1 = -1
~Add 1 to both sides
0 = 0
Therefore, all real numbers are solutions.

-1 1/5 + -3/5 in simplest form
Answer:
-1 4/5
Step-by-step explanation:
In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3 5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

what are the coordinates of the midpoint of the line segment with endpoints (2,5) and (4,-7)
Answer:
(3, -1)
Step-by-step explanation:
Let A be the midpoint and (x,y) its coordinates
● x = (2 + 4)/2 = 6/2 = 3
● y = (5 +(-7))/2 = -2/2 = -1
So the coordinates are (3, -1)
Airboats are a popular way to tour areas with shallow water. A small airboat can fit 6 people. A large airboat can fit 4 times as many people. How many more people can fit in a large airboat than in a small airboat?
Answer:
18
Step-by-step explanation:
Small airboat = 6
Large airboat = 4× the small airboat's capacity = 4×6= 24

2(a+5)=-2 Steps too please ❤️
Answer:
a=-6
Step-by-step explanation:
2(a+5)=-2 Step 1 distribute
2a+10=-2 Step 2 minus 10 on both sides
2a=-12 Step 3 divide but 2 on both sides
a=-6
Answer:
a=-6
Step-by-step explanation:
In order to solve for a, we must isolate a on one side of the equation.
[tex]2(a+5)=-2[/tex]
2 is being multiplied by (a+5). The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]2(a+5)/2=-2/2[/tex]
[tex](a+5)=-2/2[/tex]
[tex](a+5)=-1[/tex]
5 is being added to a. The inverse of addition is subtraction. Subtract 5 from both sides of the equation.
[tex]a+5-5=-1-5[/tex]
[tex]a=-1-5[/tex]
[tex]a=-6[/tex]
Let's check our solution. Plug -6 in for a and solve.
[tex]2(a+5)=-2[/tex]
[tex]2(-6+5)=-2[/tex]
[tex]2(-1)=-2[/tex]
[tex]-2=-2[/tex]
This checks out, so we know our solution is correct.
The solution to the equation 2(a+5)=-2 is a=-6
The cuboid has volume 288cm^3 (a) the cuboid has a length 12 cm and a width 5cm Calculate the height of the cuboid (b) 1cm^3 of the cuboid has a mass of 4g Work out the mass of the cuboid. Please help I am desperate
Answer:
height= 4.8cm
Step-by-step explanation:
volume= length×width× height given the volume and length and width, 288=12×5×h
288=60h
divide both sides by 60
h=4.8cm
h = 4,8 cm
m = 1152 g
Step-by-step explanation:V = l×w×h
h = V/l×w
= 288cm³/12cm×5cm
= 288cm³/60cm²
= 4,8 cm
1cm³ .............. 4g
288cm³ ........ xg
x = 288cm³×4g/1cm³ = 1152 g
