Lenny sold 576 tacos in 48 hours what was lenny's average rate of tacos sales

Divide the amount by time to get average

576 / 48 = 12

12 tacos per hour

If you want days multiply by 24

12 x 24 = 12 x 12 x 2 = 144 x 2 = 288

288 tacos per day

Hope this helps

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
