Question

How many integers greater than or equal to 1 satisfy the inequality 2x - 6 < 18 ?

Answer 1

11

Explanation:

2x - 6 < 18

Set up a spreadsheet to do the calculation for this equation based on integers greater than or equal to 1. See the attached worksheet. Set a True/False test in the third column that returns 1 if true (2x - 6 < 18?) and 0 if false.

Sun the values in the T/F column to find that there are 11 integers greater than or equal to 1 that satisfy 2x - 6 < 18.
