Answer:
x - 17.95 = 71.80, $89.75
Step-by-step explanation:
Let the original price of the headphones be x
Amount of coupon = $17.95
You pay the final amount for the headphones after using the coupon = $71.80

x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75

2x+2(x-6)=64
4x-12=64
4x=76
x=19
x-6=13
B)
20+4x+x=180
5x=160
x=32 degrees
4x=128 degrees
C)
180-62.5=117.5 degrees</span>
