Suppose you have entered an 85-mile biathlon that consists of a run and a bicycle race. during your run, your average velocity is 9 miles per hour, and during your bicycle race, your average velocity is 29 miles per hour. you finish the race in 5 hours. what is the distance of the run

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

50x5=$250

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
