Rectangle. I hope this helps.
You divide 42 miles by 12 and you get 3.5
So it would take 3 hours and 50 min
Im gonna assume you mean 6 - (1/3)x = -1. Your notation is not super clear. If so, solution is as follows:
6 - (1/3)x = -1 [subtract 6 from both sides]
-(1/3)x = -7 [multiply both sides by -3]
x = 21
The answer is “No” because the line is not proportional.
