Answer:
They'll build 66 cars in those conditions.
Step-by-step explanation:
In this case we can use a compounded rule of three to solve the problem. We need to set it up as shown bellow:
160 workers -> 32 cars -> 2 hours
220 workers -> x cars -> 3 hours
If the number of workers rise, then we expect the number of cars to rise aswel, so they're directly proportional. If the number of hours worked increase we can expect the number of cars to increase aswell, so they're directly proportional. We can now set the fractions:
(160*2)/(220*3) = 32/x
320/660 = 32/x
x = (32*660/320) = 66 cars
They'll build 66 cars in those conditions.
Answer: 42
Step-by-step explanation:
X = 2. I am pretty sure!
Hope i get brainiest!
Y= 7x - 7z -9
+9 +9 Y+9+7z /7=x
Y+9 = 7x - 7z
+7z +7z
Y+9+7z = 7x
/7 /7
