Answer 1

Answer: Choice A) 9

=================================================

Explanation:

We have some variable r that we divide over 3, and then we add on 5. Note the order of operations PEMDAS says to divide first and then add (since D comes before A in PEMDAS).

When we isolate r, we follow PEMDAS in reverse and undo everything. We undo addition by subtracting 5 from both sides

$\frac{r}{3} + 5 \le 8\\\\\frac{r}{3} + 5-5 \le 8-5\\\\\frac{r}{3} \le 3$

Then we undo the division happening to r. So we multiply both sides by 3

$\frac{r}{3} \le 3\\\\3*\frac{r}{3} \le 3*3\\\\r \le 9$

Since r is less than or equal to 9, this means that r could be 9 or smaller

Only choice A applies.
