Question

Which number satisfies the inequality 9h + 15 > 55?

Answer 1

9h + 15 > 55
- 15 - 15
9h > 40
9 9
h > 4⁴/₉

The solution set is equal to (4⁴/₉, ∞).

Answer 2

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

9h + 15 > 55

Subtract 15 from each side: 9h > 40

Divide each side by 9 : h > 40/9

Any number greater than (4 and 4/9) satisfies the inequality.
