Answer:
The probably. that a person who has been in the hospital for the future of the answers to the questions
A) -1
Because it would be fine like this:
5x - 7 = -12
5x = -12 + 7
5x = -5
x = -5 / 5
x = 1
As the three longitudinal lines are parallel:
angle 4 = 5 = 6 = 82 degree (corresponding angles) = 9 = 8 = 7 = 82 degrees (vertical angles)
and
angle 11 = 180-82= 98 degrees (linear pair)
so:
angle 10 = 11 = 12 = 98 degrees (corresponding angles) = 3 = 2 = 1 = 98 degrees (vertical angles)
.
hope you got it
So first you need to combine like terms:
7b -2/5 = 6b - 7/5
+2/5 +2/5
7b = 6b -5/5
7b = 6b -1
-6b -6b
b=-1
