Answer:
The only r-value that satisfy the given inequality is;
[tex]r=9[/tex]
Explanation:
Given the inequality;
[tex]\frac{r}{3}+5\leq8[/tex]
Let's solve by firstly subtracting 5 from both sides;
[tex]\begin{gathered} \frac{r}{3}+5-5\leq8-5 \\ \frac{r}{3}\leq3 \end{gathered}[/tex]
Then let's multiply both sides by 3;
[tex]\begin{gathered} \frac{r}{3}\times3\leq3\times3 \\ r\leq9 \end{gathered}[/tex]
Therefore, the only r-value that satisfy the given inequality is;
[tex]r=9[/tex]
