Question

Evaluate each expression if a = 9, b = 3, and c=1/3

19+6a divided by 2.

Answer 1

19 + 6x9= 73. 73 divided by 2 = 36.5

Answer 2

You want to substitute a for 9 giving you 19 + 6 * 9 / 2. Following order of operations you would do 6*9 which equals 54 and divide that by 2 which equals 27. 27+19= 46. Therefore, your answer is 46.
