25 mph

Step-by-step explanation:

.5 = 12.5

1.5 = 37.5 = 12.5 x 3  

all I had to do is times 12.5 x 2 because I found out it was just adding 12.5 ever time

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

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
