Which steps would you use to solve this equation? check all that apply. p + 7 = 12 subtract 7 from both sides of the equation. subtract 7 from 7. 7 – 7 = 0 and 12 – 7 = 5, so p = 5. substitute 12 for p to check the solution. substitute 5 for p to check the solution.

answer:

all of the answers except substitute 12 for p to check the solution.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
