i don't know if that's correct but since the diameter is 8 inches and the wheel would turn four times it will be 32
Answer:
true
Step-by-step explanation:
5x + 4x = 9x
3y + 7y = 10y
8 + 34 = 42
2x + 3x + 140 = 360 (being complete turn angle)
5x + 140 = 360
5x = 360-140
5x = 220
x = 44
now 2x = 2 × 44 = 88
3x = 3 × 44 = 132
2 hours is also 120 minutes
120/15=8
8 x 5=40
120+40=160
It will take her 160 minutes to finish, or 2 hours and 40 minutes
