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

Jul 25, 2018

$n \ge 27$

#### Explanation:

$\frac{1}{3} n \ge 9$

Multiply both sides by $\textcolor{b l u e}{3}$ to solve for $n$:
$\frac{1}{3} n \textcolor{b l u e}{\cdot 3} \ge 9 \textcolor{b l u e}{\cdot 3}$

$n \ge 27$

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

The closed circle on the $27$ means that it is a solution (and anything greater than it).

Hope this helps!
