60 miles because (20mph)((3hrs) = 60
4y+7x-3y+2x
(7x+2x)+(4y+-3y)
=9x+y
The answer is 1.4 x 10^3 Or 1400
Rewrite the equation as
(2x7) x (10^6 x 10^4) then calculate from there to get your answer
I don't see the answer choice here that 0.4 should be ,which is 4/10,once reduced by dividing both 4 and 10 by 2 ,you would get an answer of 2/5???Are you sure these choices are correct?
