Coach Wu has a total of 30 soccer balls. 9 soccer balls are white the remaining soccer balls are one of three different colors (blue, pink, or green) there is an equal number of blue, pink, and green balls. How many green soccer balls does Coach Wu have?

Number of green soccer balls = 7

Step-by-step explanation:

Total number of soccer balls = 30

Number of white balls = 9

Number of soccer balls excluding number of white balls = 30 - 9 = 21

Also, the remaining soccer balls are one of three different colors (blue, pink, or green) such that there is an equal number of blue, pink, and green balls.

Number of blue balls = Number of pink balls = Number of green balls =

Therefore,

Number of green soccer balls = 7

expression #3 is not equivalent. the others are.

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.
