Question

Solve the inequality: r/6 ≤ 3
A. r ≤ 12
B. r ≤ 9
C. r ≤18

Answer 1

The answer is C. r≤18.

You can calculate this by multiplying 6 on both sides of the inequality to isolate the variable x.

`(r)/(6)`·6≤3·6

r≤18

Answer 2

C. r ≤18

Step-by-step explanation

When solving inequalities, note better when dealing with a negative sign since the inequality changes.

For the inequality given, the solution is as follows;

r/6 ≤ 3

Multiply both sides of the inequality by 6.

r ≤ 3×6

r ≤ 18
