Question

solve the inequality: 13 - r < 82 a. r > -69 b. r < 69 c. r > 95 d. -r > 69 e. r > 69

Explanation:

Step1: Isolate the term with $r$

Subtract 13 from both sides:
$13 - r - 13 < 82 - 13$
$-r < 69$

Step2: Solve for $r$

Multiply both sides by -1 (reverse inequality sign):
$r > -69$

Answer:

A. $r > -69$
