Answer:
174
Step-by-step explanation:
(5*3*2)+(9*3*2)+(5*9*2)
The first is proportional the second is proportional and the third is not proportional
The answer really depends on what b is. Unless you give me a number for what b equals I can’t solve it.
Each hour,
x makes b/6 bearings
y makes b/4 bearings
z makes b/3 bearings
Together, each hour, x, y and z together make
b/6+b/4+b/3=b(1/6+1/4+1/3)=b(2/12+3/12+4/12)=b(3/4)=3b/4 bearings.
Time to make b bearings =
b/(3b/4)=4/3 hours = 1 hour 20 minutes.
