Answer:

I believe the answer is D because even though c and d are similar, in C, the total distance ridden is 5 miles because they rode back and forth so you add the distances. In D, you don't earn any profit because you sold the item for the original price. That is why I think the answer is D. A and B isn't giving 0 as the answer because A is 6 for the answer and B's answer is 24.

Answers:
x=22
x+4=26
6x=132

Explanation:
We learned from the question that all of the angles in a triangle add up to 180 degrees.

180=angle+angle+angle

When we plug in the values that the question gives us for the angles, we get this equation:

180=x+6x+(x+4)

After solving this equation, we get 22 as the value of x (The process of solving that equation is in the picture attached).

To solve for (x+4), we plug in the value of x, which is 22 and add 4.

(x+4)
=(22+4)
=26

And finally, to solve for 6x, we plug in 22 again:

6x
=6*22
=132

Hope this helps!
