13.6
Step-by-step explanation:
5 divided into 68 is basically the same thing as 68 divided by 5.

You are given a table in which each row represents the coordinates of points. For example, in the first line, we have x=-7 and y=5. Work through the four given equations, one at a time, subbing -7 for x and 5 for y; is the equation still true? If yes, then you have found the correct answer. B is the exception; I'd suggest you check out equations A, C and D first, before focusing on B.
Example: D: (5)-5 = 2((-7) + 7) leads to 0 = 0. Is that true? If so, D is likely the correct answer.

Answer:</h3>
<h3>
Step-by-step explanation:</h3>
We know that 
, so substitute that into the equation. 
With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, 
. This makes our equation: 
Finally, simplify the exponent. 
42/98=3/7
Have a great day :)
