Answer:
x = 
Step-by-step explanation:
Given
= x + 7 ( multiply both sides by 2 to clear the fraction )
4x - 1 = 2(x + 7) ← distribute
4x - 1 = 2x + 14 ( subtract 2x from both sides )
2x - 1 = 14 ( add 1 to both sides )
2x = 15 ( divide both sides by 2 )
x = 
Answer:
x = -19
Step-by-step explanation:
-3= 12x-5(2x-7)
Distribute
-3= 12x-10x+35
Combine like terms
-3 = 2x +35
Subtract 35 from each side
-3-35 = 2x+35-35
-38 = 2x
Divide each side by 2
-38/2 = 2x/2
-19 =x
60 goes into 195 so 60*3 is 180 and it can't go any higher so 4 is the answer

Answer:
C. 60°
Step-by-step explanation:
The angles in a triangle add up to 180°.
You are given 60° and 60°.
Add them
60 + 60 = 120
Subtract 120 from 180.
180 - 120 = 60°
