Anastasia went shopping for birthday gifts and bought three of the same board games. She also spent $9.75 on birthday cards. Anastasia spent a total of $69.60. Which equation can be used to determine b , the price of each board game? A. b+(3b+9.75)=69.6
B. (3+9.75)b=69.6
C. 3b+9.75=69.6
D. 69.6−9.75=b

D

Step-by-step explanation:

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

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.
