10 + (-5) = 10 - 5 = 5
-11 + 20 = 20 + (-11) = 20 - 11 = 9
102 + (-1) = 102 - 1 = 101
<span>-20 + 60 = 60 + (-20) = 60 - 20 = 40 </span>
The correct answer is D. You can see It is the biggest bar and so you can estimate the correct answer.
ANSWER

EXPLANATION
The given line JKL is a straight line. The angle on a straight line is 180 degrees.
This implies that the sum of the angles ![\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Solve%20for%20x%20in%20the%20equation%20above%3A%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%20x%3D180-30%20%5C%5C%20x%3D150%5Cdegree%20%5Cend%7Bgathered%7D)
That is the value of x.
You have y-4 = (x-8)
Add 4 to each side:
Y = (x-8) +4
Remove the parenthesis and combine like terms to get:
y = x-4
