Answer:
x=4
Step-by-step explanation:
Pentagon's sum of interior angle is 540°
let's add all the given degrees
100+20x+16x+16+140+160-5x=540
Collect like terms
100+16+140+160+20x+16x-5x=540
416+31x=540
31x=540-416
31x=124
x=124/31
x=4```
<span>The original cost of the camera is $120.
Explanation:
6%=6/100=0.06. This means to find 6% tax on a sale, we multiply the amount of the sale by 0.06; this gives us 0.06x, since we don't know the cost of the camera.
We know the amount of tax is $7.20, so we have the equation 0.06x=7.20.
Divide both sides by 0.06:
0.06x/0.06 = 7.20/0.06
x=120.</span>
