The length of a train car is 50.6 feet this is baffling 8 feet less than six times the width what is the width
hram777 [196]

Answer:

the width is 9 23/30 feet ≈ 9.767 ft

Step-by-step explanation:

Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...

6w -8 = 50.6

6w = 58.6 . . . . . . . add 8; next divide by 6

58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet

This is a repeating decimal: 9.766666...

The width of the train car is 9 23/30 ft, about 9.77 ft.
