She had 60 pairs of shoes before selling any
2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30
4 is the only factor common among all terms
Answer:
380
Step-by-step explanation:
.20x = 19 + .15x
.05x = 19
x = 380
500 − 250 = 250 pieces left after donation
Yolanda got 180 pieces....then Enrique got 70 pieces
So he got 70 /250 = 7/25 = 28% of the remaining candy
