Elise is making 42 chocolate ice cream sundaes. The number of quarts of ice cream she needs is directly proportional to the number of people served. Suppose it takes 3 quarts of ice cream to serve 18 people. Which statements are correct for this

situation?

the answer is 5/3x+7/5y+7

what shape is

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
