HELP PLEASE which of the following expression represents the width of the door ?
A) (3x+6)-x-x
B)(h4x-1)-x-x
C)(3x+6)+(4x-1)+(4x-1)+x+
D)(4x-1)-(3x+6)

Step-by-step explanation: For example, 5 can be written as 5/1. The natural numbers, whole numbers, and integers are all subsets of rational numbers.

Step-by-step explanation:

a= - 5 - b

Subs. the above into...

ab = - 24

(-5-b)b = - 24

Therefore b=-24 or b=19

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

a + b = - 5 → (1)

ab = - 24 → (2)

Rearranging (1) expressing a in terms of b, that is

a = - 5 - b → (3)

Substitute a = - 5 - b into (2)

b(- 5 - b) = - 24 ← distribute left side

- 5b - b² = - 24 ( subtract - 5b - b² from both sides )

0 = b² + 5b - 24 ← in standard form

0 = (b + 8)(b - 3) ← in factored form

Equate each factor to zero and solve for b

b + 8 = 0 ⇒ b = - 8

b - 3 = 0 ⇒ b = 3

Substitute these values into (3) for corresponding values of a

b = - 8 : a = - 5 - (- 8) = - 5 + 8 = 3

b = 3 : a = - 5 - 3 = - 8

Thus

a = 3, b= - 8 or a = - 8, b = 3

===========================================

Explanation:

Let x be the value of the sale in dollars.

x-1900 represents the leftover amount that is over 1900

eg: if x = 2200, then x-1900 = 2200-1900 = 300 is the the leftover amount

taking 9% of (x-1900) leads to the expression 0.09(x-1900) and this expression must be 1000 since this is the extra amount of money the salesman needs (he already has $1000 in base pay)

-------------

Solve for x

0.09(x-1900) = 1000

x-1900 = 1000/0.09

x-1900 = 11,111.11111 approximately

x = 11,111.11111 + 1900

x = 13011.1111

x = 13,011.11 rounding to the nearest cent

Answer:

 525 miles

Step-by-step explanation:

Two unit rates are given in this problem:

miles per gallon

gallons per mile

Since we want to find miles, the appropriate rate to use is miles per gallon:

[tex]distance = \frac{miles}{gallon} (gallons)\\distance = \frac{35 miles}{gallon} (15 gallons) = 525[/tex]

Let's use an equation to solve this problem.

[tex]y=24x+16[/tex]

Where x is the price of each cupcake, y is the total cost, 16 is the price of the layer cake, and 24 is the number of cupcakes.

[tex]57=24x+16[/tex]

[tex]41=24x[/tex]

[tex]x=\frac{41}{24}[/tex]

Which simplifies around to $1.71 dollars.

Hope this helps.

Step-by-step explanation:

Answer:

y=7x-27

Step-by-step explanation:

The equation of a line is given by y=mx+C where m is the gradient of the line or slope and c is the intercept on your axis. according to your question, you are given two point on (3,-6) and (5,8). so we can get the gradient m= Y2-Y1/X2-X1= gradient. so Y1= -6, Y2=8 , X1=3, X2=5

slope= 8-(-6)/5-3=14/2=7. so m=7....so the equation of line can be written in form y=7x+C. but we need to find C. C can be gotten from where the line passes through (3,-6) that is when x=3, y=-6. so we can find C from that point. -6=7(3)+C..so we have -6=21+C. C=-6-21=-27

so the equation of the line is y=7x-27

Answer:

The correct option is;

A total of forty hours a week

Step-by-step explanation:

The given information in the question are;

The number of hours of sleep Nina gets during weeknights = five hours

The number of hours of sleep Nina gets per night on weekends = ten hours

The number of days in a week = 5 days

The number of days in a weekend = 2 days

Therefore;

The number of hours of sleep Nina gets per week = 5 days × 5 hours/day + 2 days × 10 hours/day

∴ The number of hours of sleep Nina gets per week = 25 hours + 20 hours = 45 hours

The number of hours of sleep Nina gets per week = 45 hours

To better concentrate on schoolwork, Nina could get a total of forty hours a week of sleep a week to increase the number of hours she spends weekly on her schoolwork by up to 5 hours (45 hours - 40 hours).

Answer:

Step-by-step explanation:

"one half the sum of a number and 4" is (1/2)(n + 4)

"three less than the quotient of 5 and the number" is 5/n - 3

putting this all together, we get

(1/2)(n + 4) = (5/n) - 3

Answer:

b.) 1/2(n 4)=5/n−3

Step-by-step explanation:

Answer:

-x - 3

Step-by-step explanation:

(3x - 4) - (4x - 1)​ =

The first set of parentheses is unnecessary, so you can just remove it.

= 3x - 4 - (4x - 1)​

To remove the second set of parentheses, you must distribute the negative sign to its left by the terms inside the parentheses. To do this, change every sign inside the parentheses.

= 3x - 4 - 4x + 1

Now combine like terms. Terms with x are like terms and are combined together. Therms without x are like terms and are combined together.

= 3x - 4x - 4 + 1

= -x - 3

Answer:

-9

Step-by-step explanation:

Step 1 : Put like terms together

x + 9 = 21 + 3x - 4 + 10

Subtract 3x on both sides

-2x + 9 = 21 - 4 + 10

Subtract 9 on both sides

-2x = 21 - 4 + 10 - 9

Simplify

-2x = 18

Step 2 : Divide

[tex]\frac{-2x}{-2}[/tex] = [tex]\frac{18}{-2}[/tex]

x = -9

Answer:

x= -9

Step-by-step explanation:

- Put all the same signs together

x-3x = 21-4+10-9

*Quick tip:

  -when you cross a sign with a number or without a number over the equal  

   sign you have to change the sign (positive to negative and negative to    

   positive.

  -x and 1x is the same thing

- Calculate small sections by small sections

-2x = 17 + 1

-2x= 18

-2/-2x = 18/-2

x= -9

Answer:

(fog)(x) = f(g(x)) = 3(x^2 + 1 ) + 2

Step-by-step explanation:

For this problem, you simply need to understand the notation (fog)(x) is equivalent to f ( g ( x ) ).  This means you simply plug the function g(x) into each x within the function of f(x).  Let's do this:

f(x) = 3x + 2

g(x) = x^2 + 1

f(g(x)) = 3(x^2 + 1 ) + 2

(fog)(x) = f(g(x))

Cheers.

Answer:

6/25

Step-by-step explanation:

6/25

0.24... as a fraction in simplest form is 6/25.

A fraction is in its simplest form if the numerator and denominator have no common factors other than 1.

In other words, you cannot divide the top and bottom any further and have them still be whole numbers. The simplest form is also called lowest terms.

We have:

0.24 = 24/100

In this case, 24 and 100 have a common factor, which is 4. Thus, 0.24 (24/100) in simplest form will be:

0.24 = 24/100 = 6/25  (divide both numerator and denominator by 4)

Hello, I do not see a question nor a histogram for the statement/info provided. I am assuming that the question that you are referring to is "Which of these most likely describes the data shown in the histogram?"

Answer:

The correct answer would be: A, The cards are grouped into five intervals according to price. The prices of the cards  vary within each interval, and the highest frequency is 21.

Explanation:

From the histogram (below), you can observe that the highest frequency for the diagram is in fact 21, so you can eliminate answer options B and D.

You are left with either A or C, but you can tell that C is wrong as it states "The prices of the cards are  limited to a few whole number values", but in truth the histogram displays values that are decimals, the prices of the cards  vary within each interval.

Hope this helps!

Answer:

x = [tex]\frac{1}{4}[/tex] ± [tex]\frac{1}{2}[/tex][tex]\sqrt{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] (4x - 1)² = 4 ( multiply both sides by 2 to clear the fraction )

(4x - 1)² = 8 ( take the square root of both sides )

4x - 1 = ± [tex]\sqrt{8}[/tex] = ± 2[tex]\sqrt{2}[/tex] ( add 1 to both sides )

4x = 1 ± 2[tex]\sqrt{2}[/tex] ( divide both sides by 4 )

x = [tex]\frac{1+/-2\sqrt{2} }{4}[/tex]

   = [tex]\frac{1}{4}[/tex] ± [tex]\frac{1}{2}[/tex][tex]\sqrt{2}[/tex]

Answer:

4 batches

Step-by-step explanation:

First, you need to convert the mix number into a single fraction:

3 1/5 = 16/5 total barrels of coffee beans used

This allows us to divide the numbers easier in the next step.

Next, because each batch uses 4/5 of a barrel of beans, you need to divide 16/5 by 4/5:

(16/5) / (4/5) = 16/4 = 4 batches

(The fives cancel out because they are the same divisor.)
