Depends on how and what your doing
It is a rectangle so its opposite sides are congruent. Because they are congruent we can set them equal to each other and solve for x.
40 = 5x + 10
30 = 5x
6 = x
So the value of x is 6.
Answer:
60+50.45x=57.95x
Cost of Fast Internet:
$60 for installation and $50.45 per month for months =
Cost of Quick Internet:
Free installation and $57.95 per month for months =
We want to know in how many months BOTH COSTS WOULD BE SAME. So we EQUATE the expressions for both. We have:
This equation can be solved for x to find the number of months for which the internet service would cost the same.
