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

Answer:
2.5
Step-by-step explanation:
Given
See attachment for number line
Required
Determine the opposite of the point
Represent the point with x; we have to first, determine point x
From the number line:
The opposite of number x is -x
Hence, the opposite of the point is 2.5

Answer:
3.125
Step-by-step explanation:
Add 1.99 + 2.99 + 3.99 + 3.89 = 12.86
12.86 / 4 = 3.125
You divide by 4 since there are 4 terms.
Hope this helps!!
