Question

suppose that r and s are points on the number line. if rs = 5 and r lies at 13, where could s be located? if there is more than one location, separate them with commas. location(s) of s :

Explanation:

Step1: Consider right - side position

If $S$ is to the right of $R$ on the number line, we add the distance to the position of $R$. So $S=13 + 5$.
$13+5=18$

Step2: Consider left - side position

If $S$ is to the left of $R$ on the number line, we subtract the distance from the position of $R$. So $S=13 - 5$.
$13 - 5=8$

Answer:

8,18
