URGENT Gabe is driving toward San Francisco at a speed of 48 mph. If his dad left an hour later at a speed of 72 mph, how long will it take for Dae’s dad to catch up?

2 hours

Step-by-step explanation:

48=72t-48t

48= (72-48) x t

48=24t

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

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
