I don't know what the answer is
Answer:
Step-by-step explanation:
1.
hours 1/2 1 1.5 2 2.5 3 3.5 4
charges 3.25 6.50 9.75 13.0 16.25 19.50 22.75 26.00
2. The garage rate of parking is ;
$3.25 = 0.5 hr
?=1----------------------twice the charge for half an hour
=2*3.25=$6.50
$6.50 per hour
3.
$6.50=1 hour
$42.25=?------------------cross multiply
$(42.25*1)÷$ 6.50 = 6 hrs 30 min

x = 12</h3><h3>
Angle B = 45 degrees</h3>
===========================================================
Explanation:
Angles A and B are alternate exterior angles.
Due to the parallel lines, alternate exterior angles are congruent
A = B
5x-15 = 2x+21
5x-2x = 21+15
3x = 36
x = 36/3
x = 12
Use this x value to find the measure of angle B
angle B = 2x+21
angle B = 2*12+21
angle B = 24+21
angle B = 45 degrees
As a check,
angle A = 5x-15
angle A = 5*12+15
angle A = 60-15
angle A = 45 degrees
Since A and B are both 45 degrees, this confirms the correct x value
