Question

We know that CB = 2(x − 1), so we can substitute in our x-value (it's 9) to solve for CB. CB = ?

Answer 1

CB equals 16.

Step-by-step explanation:

To solve for CB, we substitute the given value of x (which is 9) into the equation CB = 2(x − 1).

CB = 2(9 − 1) = 2(8) = 16.

So, CB equals 16.
