Question

Which of the r-values satisfy the following inequality?

r/3 + 5 <_ 9
Choose all answers that apply:

Answer 1

9

Explanation:

r/3 +5 ≤ 8

Subtract 5 from each side

r/3 +5 -5≤ 8-5

r/3 ≤ 3

Multiply each side by 3

r/3 *3 ≤ 3*3

r ≤ 9

The only value that is less than or equal to 9 is 9
