The answer is D because the two sides add up to 180.
Answer:
a = -1
Step-by-step explanation:
Combine like terms 6a + 5a = 11a
11a = -11
Divide -11 by 11
-11/11 = -1
Answer:
2/7
Step-by-step explanation:
You would add what is in the parenthesees and you get 6/14 and if you simplify you get 3/7. So you would do 5/7 -3/7
Because both lines are parallel, if you add the 5x+5 to the 115 those would equal 180 degrees
so you have 5x+5 + 115 = 180
combine like terms:
5x + 120 = 180
subtract 120 from both sides
5x = 60
x = 60/5
x = 12
