1st 306.36 2nd 10.78 3rd 355.25
Step-by-step explanation:
bc i just skipped and it showed me the answers
The answer is B. They are saying to cube the difference therefore you have (x-43) cubed
Let x = speed and y = distance
y = x * 45
y = (x - 4) * 70
45x = 70x - 280
-25x = -280
x = 11.2
Put it back into the first equation:
y = 11.2 x 45
y = 504miles
Hope this helps! Any questions let me know :)

95 over 2
because if it is 47 you double that since the denominator is 2 then you add the numerator and now you have your answer.
