Step-by-step explanation:

Mar 10, 2019 · x = (2/5)y + 2 5x + 3z = -5 5[(2/5)y + 2] + 3z = -5 2y + 10 + 3z = -5 2y + 3z = -15 Since this is the same as the second equation if you multiply both halves by -1, we essentially have two unknowns with one equation which has infinite solutions. Therefore the set of …

hows it hangin lol

step-by-step explanation:

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
