Answer:
88
Step-by-step explanation:
1.50c + 4.00a = 5,050
c + a = 2,200
-1.50 (c + a = 2,200)
1.50c + 4.00a = 5,050
-1.50c - 1.50a = -3,300
2.5a = 1750
a = 700
c + 700 = 2,200
c = 1500
700 adults and 1500 children attended the fair.
90 degrees because you can see at the part that is in the middle it is 90 degrees
Its 157, because 180-23= 157 degrees.
