Question

If x = yand y = z, which statement must be true?

O A. -x=-z

O B. z=x

O c. x=z

O D. -x=z

Answer 1

The answer is C. x=z

Explanation:

The correct answer is C. x=z.

Since x = y and y = z, then x = z. This is the transitive property of equality.

Here is a more detailed explanation:

The transitive property of equality states that if a = b and b = c, then a = c.

In this case, x = y and y = z. Therefore, x = z.
