Question

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

Answer 1

`n <= 27`

Explanation:

To solve this, multiply both sides by `color(blue)3`:
`1/3n color(blue)(*3) <= 9 color(blue)(*3)`

`n <= 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!
