First, we want to divide 99 by 11, in order to get 9. Then, we multiply 9 by 2/3 to get 6.
6 cups would be the amount of milk we need for 99 cookies.
I hope this helped! :>
It's important to do the same thing to both sides in an equation so it stays equal,
so first you group like terms (x with x and #'s with #'s)
so
2x+5x+3x+20=95+25
10x+20=120
subtract 20 from both sides
10x=100
divide both sides by 10
x=10
The answer to that would be 14.66666666666667
