3 Quartz of 10% butterfat is mixed with some unknown amount of 3% whole milk. If there are 8 quarts of the total mixture, how many quarts of whole milk were used?
What is the % fat In the final mixture?

Correct Whole milk 5 quartz and 5.625%

Step-by-step explanation:

When we subtract from the total mixture 8  the quantity 3 of the butterfat  we will get 5 quartz of the whole milk.

We will solve the problem using the following equation:

3 · 10 + 5 · 3 = 8 · x  ⇒ 30 + 15 = 8 x ⇒ 8 x = 45

x = 45 / 8 = 5.625%

x = 5.625%

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

it's both, now can you answer my most recent question?
