the answer is 8x-4 because
3x+−5+5x+1
=(3x+5x)+(−5+1)
=8x+−4
Answer:
w = 42
Step-by-step explanation:
A linear pair is a pair of adjacent angles which add up to 180 degrees(supplimentary).
Given m<1 = w + 5, m<2 = 3w + 7, and the fact that m<1, and m<2 form a linear pair. This relationship can be given by:
m<1 + m<2 = 180.
To solve just substitute the expressions given by the angles, and solve.
m<1 + m<2 = 180

(w+5)+(3w+7) = 180 →
4w + 12 = 180
