<span>2-b=c -(13-b)=c2-b=-13+b2b=15b=15/2c=2-15/2=4/2-15/2=-11/2 C cannot be negative, so 2-b not >0 and 13-b not <0
Both 2-b and 13-b cannot be both positive and negative, because 2-b=13-b is wrong
-(2-b)=c, 13-b=c, -2+b=13-b, 2b=15, b=15/2, c=13-b=13-15/2=26/2-15/2=11/2So, finally b=15/2 and c=11/2Answer is abs(x-15/2)=11/2

Answer:
<h2>C. 3x + 80 + 2x = 180</h2>
Step-by-step explanation:
The straight line creates an angle of 180 °.
Therefore from the picture we have the equation:
3x + 80 + 2x = 180 <em>subtract 80 from both sides</em>
5x = 100 <em>divide both sides by 5</em>
x = 20
