Question

What is the answer to -p + 7 ≤ -8.5

Answer 1

Explanation:

-p + 7 ≤ -8.5

-p ≤ -8.5 - 7

-p ≤ -15.5

*divide both sides by -1*

p ≥ 15.5

Answer 2

`-p + 7 \leq -8.5`

Subtract 7 from both sides:

`-p+7-7\leq -8.5-7`

`-p\leq -15.5`

Divide both sides by -1:

`(-p)/(-1) \leq (-15.5)/(-1)`

`\fbox{p}\geq \fbox{15.5}`
