If the distance of laps is 8, and the time was 20 minutes, what is the minutes per lap

2.5 minutes per lap

Step-by-step explanation:

Since you are dividing time over distance, you divide 20/8 to get 2.5 minutes per lap.

step-by-step explanation:

this is not possible to solve with the info given.   you need at least an one angle somewhere.

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
