Answer:
13
Step-by-step explanation:
We're trying to find the distance between points X and Y. Or the distance of X-Z plus Z-Y.
Lets find the distance of X-Z
6-2=4
Now lets find the distance of Z-Y
15-6=9
Now we add the distances
4+9=13
C is the correct answer, -7 is smaller than 7.
when u have a common a denominator then you just add the numerator that would be 7 and 9. 7 + 9= 16
so ur solution would be 16/22 and then u would simplify by dividing both values by 2.
so the solution is8/11
