Question

solve for r and graph the solution.
3 < (r + 8)/3 < 4
plot the endpoints. select an endpoint to change it from closed to open. select the middle of a segment, ray, or line to delete it.

Explanation:

Step1: Multiply each part by 3

$3\times3<\frac{r + 8}{3}\times3<4\times3$
$9

Step2: Subtract 8 from each part

$9-8$1

Answer:

The solution for $r$ is $1
