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.

Accepted Answer

# Explanation:
## Step1: Multiply each part by 3
$3	imes3<\frac{r + 8}{3}	imes3<4	imes3$
$9<r + 8<12$
## Step2: Subtract 8 from each part
$9-8<r+8 - 8<12-8$
$1<r<4$

# Answer:
The solution for $r$ is $1<r<4$. On the number - line, the endpoints at $r = 1$ and $r = 4$ are open circles (since the inequality is strict, i.e., $<$ and not $\leq$), and the line segment is drawn between them.
