Answer:
55% decrease
Step-by-step explanation:
To find the percent decrease
Take the original price and subtract the new price
140-63 =77

.55*100 = 55%
55% decrease since the price got lower
Answer:
72 games won
Step-by-step explanation:
Answer:
[2(x+10)]°+(3x-30)°=180°[vertically opposite angle]
2x+20+3x-30=180°
5x-10=180°
5x=180-10
5x=170
x=170/5
x=34
