Answer:

C

Step-by-step explanation:

Since z = 7 the equation would be 3(7) - 3

You would multiply 3 with 7 and get 21

Then you would subtract 3 from 21 and get 18

hope this helps.

Points Y and Z are the same distance from point X on a number line. The coordinate of point X is 3 and the coordinate of point Y

zaharov [31]

Coordinate of point Z is 8. That is because the distance from point X to point Y is 3-(-2)=3+2=5, and same is from point X to point Z: 3+5=8. So the answer is Z=8.
