-2(y-1) = 9
Use distributive property:
-2y + 2 = 9
Subtract 2 from both sides
-2y = 7
Divide both sides by-2:
Y = -7/2

3/20 = 15/100 = 0.15 = 15%
hiiiiiiiiiiiiii
a. x = 4 b. x = 7
a. They are both congruent right angles because of the alternate exterior angles theorem
90-4 = 86
86/21 = 4
b. The angles are congruent because of the corresponding angles postulate
75+2 = 77
77/11 = 7
