<span>Whena line gets crossed by a tranversal line, the angles on the diagonal are equal to one another.

This means that (2x + 1)</span>°<span> will be equal to 85</span>°

so we can set up the equation 2x +1 = 85 and sove for x

2x = 84 x = 42

Now, take the fact that lines on a line must add up to 180° so we can get the equation (3y + 5) + 85 = 180 and sove for y.

3y + 90 = 180 3y = 90 y = 30

Answer: x = 42, y = 30

The cost of having your car towed is 45 to hook up the carand then 3.50 per mile towed. which equation models your total cost?

Greeley [361]

Answer B is correct --> y = 3.50x + 45

y represents the total cost
x represents the number of miles towed (since it costs 3.50 per one mile, that's why the variable x needs to be here because we don't know how many miles we'll have yet)
