<span>B. 16 quarts of the 2% milk and 24 quarts of the 7% milk
First, let's create an equation to solve.
x = quarts of 2% milk
(40-x) = quarts of 7% milk
So we have the equation
x*2 + (40-x)*7 = 40*5
Now to solve for x
x*2 + (40-x)*7 = 40*5
x*2 + 7*40 - 7*x = 40*5
x*2 - 7*x = 40*5 - 7*40
-5*x = - 2*40
x = 2*8
x = 16
So we need 16 quarts of 2% milk and 40-16 = 24 quarts of 7%, which matches option "B".</span>
Answer:
x =
Step-by-step explanation:
To solve for x, we need to isolate it [get it alone on one side]
We should start by simplifying (combining the like-terms of our equation):
5 + 5 = 5x + 5 - 2
10 = 5x + 3
- 3 - 3 (subtract 3 from both sides to isolate x)
7 = 5x
÷5 ÷5 (divide both sides by 5 to find "1"x)
So, x =
(x = 7/5)

Hello there! :)
Answer:
1. 
2. 
Step-by-step explanation:
1. 3/5+4/15
First, you multiply by numerator and denominator.
3*3=9
5*3=15

Then, you had to combine by the fractions.

Add by the numbers from left to right.
9+4=13
<u><em>13/15 is the final answer.</em></u>
______________________________________________
2. 5/6-1/4
First, you multiply by 2 both sides of numerator and denominator.
5*2=10
6*2=12
10/12
3/12

Subtract by the numerator.
10-3=7
<em><u>7/12 is the final answer.</u></em>
