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
So to find the original price of the headphones, the equation will be
x - 17.95 = 71.80
x = 17.95 + 71.80
x = $89.75
The original price of the headphones would be $89.75
221 seconds to x minutes.
To convert the seconds into minutes, you'd need to multiply by something that would cancel out the seconds. So if the 221 seconds are the numerator right now, you'd have to multiply by something with the seconds in the denominator.
The only one here that makes sense is
D. 1 minute/60 seconds

You are given the length of every side, except for two, that can be easily derived from the others:
- The long horizontal side on top is the sum of the three beneath it, so it is

- The vertical one on the right is, similarly, the sum of the opposite side to the far left, and the two small sides near it:

The sum of all sides, including these two, will give you the perimeter of the polygon.
