collect the like terms
4x - 9 = 6-x
4x + x= 6+9
and then complete the equation
5x = 6 + 9
5x = 15
x = 15 ÷ 5
x = 3
Are you taking the state test-
If vertical angles are congruent you know
84=4x
21=x
You also know that angle M is supplementary to the angle
, measuring 84. Supplementary means it adds to 180 so if you take the difference you get
180-84=M
96=M
Also M is vertical to the last unknown angle so since vertical angles are congruent the last angle is also 96
The answer is C
Since we don’t know how much supplies cost in general it would be better to first find out how much the painter charges for the 5 hours
15.28 x 5 = 76.45$
Now that we know that we just need to solve for the difference. So subtract the total cost to the amount he charged for 5 hours of work
157.18 - 76.45 = 80.73
