<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:
42
Step-by-step explanation:
first we calculate what is 20% of 35 is then we add it to 35 to find the increased number
35 ÷ 100 = 0.35 this multipled by 20 = 7
35 + 7 = 42
The mean is 10.
To find the mean you add up all the numbers and divide by how many sets of numbers there were.
8+10+11+8+13=50
50/5=10.
Answer:
1) 6(3x-2)
2) 24(x+2)
3) 9(5x−9) or 9(5x+9) if you meant to put addition.
4)8x+15
Answer:
f(x) 3x 10
Step-by-step explanation:
x = the number
the function = Three time a number plus 10.
f(x) = 3x + 10
