Write and solve an equation to find the number of miles you must drive to have the same cost for each of the car rentals. Let m represent the number of miles.
$20 plus $0.50 per mile
$30 plus $0.25 per mile
Equation

m=40 miles

Step-by-step explanation:

the cost of 1 car=20+0.50m

the cost of second car=30+0.25m

NOW:-

20+0.50m=30+0.25m

0.50m-0.25m=30-20

0.25m=10

m=10/0.25

m=40 miles

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
