Answer:
m=-8
Step-by-step explanation:
im assuming the equation is: [tex]\frac{9}{8} m-\frac{1}{6} m=-4-\frac{11}{3}[/tex]
find common denominators i choose 24
9/8 = 27/24
1/6 = 4/24
11/3 = 88/24
4 = 96/24
now start solving:
(Note that because denominators are the same you can just ignore them and focus on the numerator)
simplify (27/24)m - (4/24)m to (23/24)m
simplify -(96/24) - (88/24) to -184/24
now you are left with 23/24 m = -184/24
get rid of denominators 23m=-184
Divide -184 by 23 to get m= -8

Solve for :
9x - 3 - 8x = 7 - X
A. X=-7
B. x = -2
C. X=4
D. x= 5
pls help me my grade is depending on it
Answer:
d. x = 5
Step-by-step explanation:
Solve for x:
x - 3 = 7 - x
Hint: | Move terms with x to the left hand side.
Add x to both sides:
x + x - 3 = (x - x) + 7
Hint: | Look for the difference of two identical terms.
x - x = 0:
x + x - 3 = 7
Hint: | Add like terms in x + x - 3.
x + x = 2 x:
2 x - 3 = 7
Hint: | Isolate terms with x to the left hand side.
Add 3 to both sides:
2 x + (3 - 3) = 3 + 7
Hint: | Look for the difference of two identical terms.
3 - 3 = 0:
2 x = 7 + 3
Hint: | Evaluate 7 + 3.
7 + 3 = 10:
2 x = 10
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 2 x = 10 by 2:
(2 x)/2 = 10/2
Hint: | Any nonzero number divided by itself is one.
2/2 = 1:
x = 10/2
Hint: | Reduce 10/2 to lowest terms. Start by finding the GCD of 10 and 2.
The gcd of 10 and 2 is 2, so 10/2 = (2×5)/(2×1) = 2/2×5 = 5:

Suppose you take $25,000 and deposit some of it into a savings account that pays 2.2% interest. You then take the rest of the money and deposit it in a CD that pays 3.05% interest at the end of 10 years the value of both accounts is $31,648. How much was deposited into each account?
Answer:
The amount deposited in the savings account is $11,494.12
The amount deposited in the CD account is $13,505.88
Step-by-step explanation:
Firstly, let’s calculate the amount of interest;
Interest = Amount at end of 10 years - amount deposited= 31,648 -25,000 = 6,648
Let the amount deposited in the savings account be $x while the amount deposited in the CD account be $y
Mathematically;
x + y = 25,000 ••••••••••(i)
Now the formula for simple interest is;
PRT/100
where P is the amount deposited, r is the rate and T is the time
On the savings account, amount of interest generated will be;
(x * 2.2 * 10)/100 = 22x/100
On the CD act, amount of interest generated will be;
(y * 3.05 * 10)/100 = 30.5y/100
The addition of both give the total interest;
22x/100 + 30.5y/100 = 6648
Multiply through by 100
22x + 30.5y = 664800 •••••••(ii)
From i, x = 25,000 - y
Substitute this into ii
22(25000-y) + 30.5y = 664800
550,000 -22y + 30.5y = 664,800
8.5y = 664,800-550,000
8.5y = 114,800
y = 114,800/8.5
y = $13,505.88
x = 25,000 -y
x = 25,000 - 13,505.88
x = $11,494.12
According to data from the U.S. Census Bureau, in 2010 21,495 workers in Wake County had a daily commute between 45 and 59 minutes. By 2016 the number of workers with this long of a commute had increased by 82%. How many Wake County workers had a 45-59 minute commute in 2016?
=======================================================
Explanation:
Ignore the "45" and "59" as they aren't used in this problem. The year numbers don't matter either. These numbers are either thrown in as filler or distraction.
We're basically being asked "we started with 21,495 and increased by 82%, what is the new value?"
Take 82% of this to get 0.82*21495 = 17,625.9 which rounds to 17,626 since it doesn't make sense to have a decimal or fractional portion of a person. So the number of workers has increased by about 17,626 people.
Add this to the original amount to get 21,495 + 17,626 = 39,121 which is the answer
--------------
As a shortcut, you could multiply 21495 by 1.82 to indicate an 82% increase
1.82*21495 = 39,120.9 which rounds to 39,121

This week at HEB, pork chops cost $1.60 per pound. Steve bought 2 1/4 pounds of pork chops. If he paid with a $10 bill, how much change did he receive?
Answer:
He received $6.40 in change.
Explanation:
Since he bought 2.25 pounds, you multiply that by 1.6 to get a sum of 3.6. Since he paid with a ten dollar bill, and he only has to pay 3.60, they will give him back 6.40 in change.

my ones digit is 2 more than my thousand digit. the sum of my ones and thousand is my hundreds digit. 3 less that my hundreds digit is my tens digit. my Hundreds thousand and ten thousand are the same. guess what number I can be.
Answer:
No answer. See below.
Step-by-step explanation:
This number is in the ten-thousands, so it has 5 digits.
Let the number have the form
abcde, where
a = ten-thousands digit
b = thousands digit
c = hundreds digit
d = tens digit
e = ones digit
"my ones digit is 2 more than my thousand digit."
e = b + 2
"the sum of my ones and thousand is my hundreds digit."
e + b = c
"3 less that my hundreds digit is my tens digit."
c - 3 = d
"my Hundreds thousand and ten thousand are the same."
c = b = a
We have 4 equations:
e = b + 2
e + b = c
c - 3 = d
c = b = a
Using the last equation, replace every c and b with a in the first 3 equations.
e = a + 2
e + a = a
a - 3 = d
Using the second equation, subtract a from both sides.
e = 0
Substitute e = 0 in the first equation.
0 = a + 2
a = -2; b = -2; c = -2; d = -5
Since a digit cannot be negative, there is a problem with this question.

You run to the store on your way home from school. You want to buy some Doritos. Should you buy the regular size bag or the party size bag? Calculate the unit price for each size and determine which one is the better buy. 15 oz. Party Size Doritos $3.98 9.75 oz. Doritos $2.98
Answer:
15 ounce bag is cheaper per ounce than 9.75 ounce bag.
Step-by-step explanation:
For this problem, you should simply take the cost divide by the size for each to find the price per ounce.
$3.98 / 15oz == $0.265 per ounce
$2.98 / 9.75oz == $0.306 per ounce
Note that the 15 oz bag is a better price per ounce than the 9.75 oz bag.
As to what bag you should buy, that really should depend on more factors than just what's best per ounce. For instance, are you really hungry enough for 15 ounces of doritos, or will 9.75 do just fine? Also, do you even have the extra dollar it would cost to buy the bigger bag? Just some stuff to think about.
Cheers.

The length of a rectangular classroom floor is 6 feet more than twice the width the perimeter is 30 feet. What is the length and width of the classroom?
Answer:
Length = 12.75 feet
Width= 2.25 feet
Step-by-step explanation:
Let the length = x
Let the width= y
The length of a rectangular classroom floor is 6 feet more than twice the width
X= 6+2y
The perimeter is 30 feet.
Perimeter= 2(length+width)
Perimeter= 2(x+y)
30= 2x +2y
But x= 6+2y
30 = 2(6+2y) +2y
30= 12 +4y +4y
30-12= 8y
18= 8y
2.25 = y
30= 2x +2y
30= 2x +2(2.25)
30- 4.5= 2x
25.5= 2x
12.75= x
Length = 12.75 feet
Width= 2.25 feet
