four pieces of pie were eaten from a pie cut into equal parts. The 5 pieces that remained created an angle that measured 200°. What was the angle measure of one piece of pie

Step-by-step explanation:

The 5 pieces that remained created an angle that measured 200 degree means that the 4 pieces made 360-200 degrees 160o.

If all four made 160 then each has to be 160/4 = 40o

200/5 also gives you 40 (the five remaining)

360/9 would also give you 40 9the 5 remaining and the 4 eaten)

I hope this helps

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
