The question is in the picture

(CHOICE 4) 6a - 4b + 11

Step-by-step explanation: Lets first combine like terms using the commutative and associative properties.

(8a - 3b + 7) - (2a + b - 4)

Distribute negative sign.

8a - 3b + 7 - 2a - b + 4

Reorder and then combine like terms.

(8a - 2a) + (-3b - b) + (7 + 4)

6a - 4b + 11 ( because it is simplified to a point where it is solved.)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw
