Hey I need help on these 4 questions Make sure that you put what question number by the answer

Step-by-step explanation:

#8- No, because you cannot make equivalent fractions out of the two fractions.

#9- Cross Multiply: 3v=15, v=5

#10- Yes, equivalent fractions can be made out of these (For 8/3, multiple numerator and denominator by 10 to get fraction 80/30)

#11: Cross Multiply once more. 72=9v, v=8

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.
