What must you do to the first inequality to get to the second inequality? A. N 4 <5;n<20 b. − n 4 <5;n>−20 A. A. Add

A. You have two inequalities:

$\dfrac{n}{4}$
$n$

If you multiply the first inequality by positive number 4 (multiplying inequality by positive number doesn't change the inequality sign), then you get the inequality

$4\cdot \dfrac{n}{4}$

B. You have two inequalities:

$-\dfrac{n}{4}$
$n>-20.$

If you multiply the first inequality by negative number -4 (multiplying inequality by negative number changes the inequality sign), then you get the inequality

$-4\cdot \left(-\dfrac{n}{4}\right)>-4\cdot 5,\\ \\n>-20.$
