Use the properties of operations to add 9(k + 1/3) + 10(1/2k - 1).

Question

A. 14k + 13
B. 14k - 7
C. 19 1/2k - 2/3
D. 14k - 2/3

Answer 1

First, distribute the coefficients:

9(k) + 9(1/3) + 10(1/2k) - 10(1)

Simplify:

9k + 3 + 5k - 10

Combine like terms:

14k - 7

Therefore, the answer is B. 14k - 7.
