Two trains leave the station at the same time, one heading west and the other east. The westbound train travels  18  miles per hour slower than the eastbound train. If the two trains are  300  miles apart after  2  hours, what is the rate of the westbound train? Do not do any rounding.

b. x + 1

step-by-step explanation:

i'am smart

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

you can use a^2+ b^2=c^2

really your just stupid if you don't know this
