Answer:
The expression for the number of mountains Gary height is 3x-8
Explanation:
Let x be the number of mountains that Angela height
We are given that Gary height 8 less than 3 times the number of mountains that Angela height
So, 3 times the number of mountains that Angela height =3x
So,8 less than 3 times the number of mountains that Angela height = 3x-8
So, Gary's height = 3x-8
Hence the expression for the number of mountains Gary height is 3x-8
