Question

Noya needs to determine the number of books that will fit into a box. If the box has a length of 18 inches and each book is 2/9 of an inch thick, which expression can be used to determine the number of books that will fit into the box?

Answer 1

2/9 x = 18; If the total amount of space is 18 inches, and each book is 2/9ths of an inch thick, you have to use x to figure out the missing value of how many books will fit

Answer 2

- First we know that each book is 2/9 inch thick
- The total length of the box is 18 inches
- And we can fill the box with x Amounts of 2/9 inch books as long as the total length DO NOT SURPASS 18 inches

So, the expression would be


`2/9 x \leq 18`

In which x is the total number of books
