Question

3 < 1.5p - 9

Explanation:

Step1: Add 9 to both sides

$3 + 9 < 1.5p - 9 + 9$
$12 < 1.5p$

Step2: Divide by 1.5 on both sides

$\frac{12}{1.5} < \frac{1.5p}{1.5}$
$8 < p$

Step3: Rewrite inequality (optional)

$p > 8$

Answer:

$p > 8$
(To graph this on the number line: Draw an open circle at 8, then shade all values to the right of 8.)
