Arecipe calls for 2 cups of flour to make 24 cookies. write and solve a proportion to find how much flour is needed to make 54 cookies.
a. 2/24 = x/54; x = 4 1/2 cups
b. 2/54 = x/24; x = 8/9 cup
c. 2/54 = 24/x; x = 27 cups
d. 2/24 = 54/x; x = 648 cups

The graph below could be the graph of which exponential function?

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.
