The average amount of of time brian spent in line skating for one week was thirty minutes. during the next week, the difference between the average and actual time spent skating was 4.2 minutes, -4 1/3 minutes, -4 1/2 minutes, and 4.75 minutes. label these difference in order form least to greatest.

-4 1/3 minutes,-4 1/2 minutes, 4.2 minutes,4.75 minutes.

that's the order!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

idk lol xd
