Question #47bbb

Answer 1

Any number greater than 40.5

Explanation:

The first term can be written as N + 81
The second term can be written as 3 N

The inequality then can be written as

N + 81 > 3N Subtract N from both sides giving
`N- N + 81 > 3N - N` This results in

`81 > 2N` Divide both sides by 2

`81/2 > 2N/2` ( since dividing the > by a positive does not change the direction of the sign it remains > ) This results in

`40.5 > N` or

`N < 40.5`
