Question

Tiana is thinking of a number, which she calls n. She subtracts 5 and then finds half of the difference. Which expression represents Tiana's number? 1 (n-5) c) What is Tiana's final number if her starting number is 23? Tiana's final number is ?​

Answer 1

1/2(n-5)

9

Explanation:

n less 5 = n - 5

if she finds the half of the difference, divide the difference by 2 = 1/2(n-5)

If n = 23

1/2 x (23 - 5)

= 1/2 x 18 = 9
