Answer:
x = 19
Step-by-step explanation:
The marked (consecutive interior) angles will be supplementary when the lines are parallel.
(3x +10)° +(5x +18)° = 180°
8x = 152 . . . . . . . . . . . . . . . divide by °, subtract 28
x = 19 . . . . . . . . . . . divide by 8
X equals 5 8/11 because if you simplify the equation you get 10 1/2=3 2/3x. divide and get the answer
Answer:
93
Step-by-step explanation:
The absolute value of any number will always be positive. Therefore, it is automatically 93.
6+6(-n+6)= 6 + (-6n) + 36
15 - 6 - 36 = (-6n -3n)
-27 = 9n
-3 = n
