Which system of equations is represented by lines p and r? A.9x−4y=−9 2x+4y=15

B.3x−y=−12 7x+3y=21

C.2x−y=−8 2x+y=7

D. x−2y=−8 6x+5y=30

answer: you need to organize this better it does not make sense.

step-by-step explanation: ?

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.

the answer is 40.
