Question

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

Answer 1

`n >= 27`

Explanation:

`1/3n >= 9`

Multiply both sides by `color(blue)3` to solve for `n`:
`1/3n color(blue)(*3) >= 9 color(blue)(*3)`

`n >= 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!
