D. X = 8 , Y = 6
3x - 14 = x + 23x - x = 2 + 142x = 162x / 2 = 16/2x = 8
To check: 3x - 14 = x + 2 ; 3(8) - 14 = 8 + 2 ; 24 - 14 = 10 ; 10 = 10
4y - 7 = y + 114y - y = 11 + 73y = 183y / 3 = 18 / 3y = 6
To check: 4y - 7 = y + 11 ; 4(6) - 7 = 6 + 11 ; 24 - 7 = 17 ; 17 = 17
hopes it helps:)
U,U you need to divide how many cards in total the subtract and mulitply them
The answer is D 16a: 1,2,3,4,8,16 and 18ab:1,2,3,46,9,18 a,b
7 or more laps. you can find this by multiplying 6 x 4 & anything above that would work too
C) it changed 0 feet
The overall change would be 0; first it would be up 750, but then coming back down 750 effectively cancels that change.
