You enter a bicycling race. You ride at 1 meters per second, while getting a 3 meter head start. Sammy does not receive a head start and cycles at 5 meters every 2 seconds. The race is 15 meters long. PLEASE HURRY

3because it's 5 x 15 it take 3 sec to get to 15

the answer is d

step-by-step explanation:

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
