The answer is D, x=12. There's a lot of little math involved but hope it helps!!
If the total amount of points in a test is 140, and we want to find 10% of those points, we can do the following to figure out how much points the question is worth...
140 points x 10% = 140 x 0.1 = 14 points for the short-answer quesion.

Answer: 
<u>Step-by-step explanation:</u>


The equation would have infinite solutions.
First, distribute on both sides, and you get 12x - 6 = 12x - 6.
There are two ways to do this from here. first is: you add six to both sides and they'll cancel out, and you'll have 12x = 12x. Then you divide by 12 on both sides and get x = x. When the two sides equal the same thing, there are infinite solutions.
Or, we can do the easy way. As you can see, 12x-6 = 12x-6. Both the sides are clearly the same, so we actually don't need to do the rest.
ANSWER: infinite solutions
