Answer:
x = 2/3
Step-by-step explanation:
combine -3 and 1. We get -2 there, and now have:
-2 + 10x = x + 4.
Combining the x terms, we get 9x = 6, so that x = 6/9, or x = 2/3
Hello there! Your answer should be 4 mph. Reasoning:
2 = (20 - x) * t
3 = (20 + x ) * t
Time is the same for both equations. Solve for T.
2/(20-x) = 3/(20+x)
the answer is 4 mph.
Please tell me if I was right!
