# How do you solve and graph 1/3n<=9?

Jul 21, 2018

$n \le 27$

#### Explanation:

To solve this, multiply both sides by $\textcolor{b l u e}{3}$:
$\frac{1}{3} n \textcolor{b l u e}{\cdot 3} \le 9 \textcolor{b l u e}{\cdot 3}$

$n \le 27$

This can be said as "$n$ is less than or equal to $27$."

Here's a graph of it on a number line:

The closed dot means that $27$ is one of the answers (and anything less than it).

Hope this helps!
