Which number satisfies the inequality 9h + 15 > 55?
zalisa [80]

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 :                  <em>  h > 40/9</em>

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