Use the properties of operations to add 9 (k + 1/3) + 10(1/2 * k - 1) . (1 point)
O 14k + 13
O 14k - 7
O 14k - 2/3
O 19 1/2 * k - 2/3
To simplify the expression 9(k + 1/3) + 10(1/2 * k - 1), we can distribute the 9 and 10 to the terms within the parentheses:
9(k) + 9(1/3) + 10(1/2 * k) - 10(1)
Which simplifies to:
9k + 3 + 5k - 10
Combining like terms:
(9k + 5k) + (3 - 10)
Which simplifies to:
14k - 7
Therefore, the correct answer is 14k - 7.
