Question

Solve the inequality.

r – 9 ≥ 11




Group of answer choices

r ≥ 20

r ≤ 20

r ≥ 2

r ≥ 11

Answer 1

r is greater than or equal to 20
you’d add 9 on both sides to isolate r .

Answer 2

r
`\geq` 20

Explanation:

You have to isolate the variable on one side, so you need to add 9 on both sides.

r - 9 + 9 = r - 0 = r

11 + 9 = 20

So, r
`\geq` 20
