(x - 20°
52°
line 2
What value of x will make line 1 parallel to line 2?
A. 32
B. 58
C. 72
D. 148

answer:      

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

r and t.

both are 64 degrees.

the answer is 18 units because there are 18 small cubes inside the rectangle
