0.17/30 = x/450 <em>Use proportion</em>
76.50 = 30x <em>Cross multiply</em>
2.55 = x <em>Divide 30 both sides</em>

7.5 minutes call would cost 2.55
On the left side use distributive property:
3(n) + (3)(4) = -6 + 15n
3n + 12 = -6 + 15n
Subtract 3n:
12 = -6 + 12n
Add 6:
18 = 12n
Divide 12:
18/12 = n
You can simplify it further:
n = 3/2 or 1.5
Step-by-step explanation:

Answer:
The expression for the number of mountains Gary height is 3x-8
Step-by-step 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
