I believe the answer is B.) <span>The quantity of distance measures in miles depends on the quantity of time measures in hours. This is because when trying to find speed a person must know the distance and the time that the object/person traveled that distance which the time is mostly measured in hours.

Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
You would see the square root of 13 and it would be 3.60 which squared would make 12.96 so round up and you will get 13
