I’m gonna kill mysel7 if I don’t get the answer I need to finish this test :( (7r-5)° (6r+4)°

r = 9

Step-by-step explanation:

Vertical angles are always congruent which means 7r-5 = 6r+4, so we can use this equation:

7r-5 = 6r+4

-6r      -6r

r - 5 = 4

   +5   +5

r = 9

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
