Question

Determine which number is the solution of the inequality: f + 2 < 9

Answer 1

6 and less will give you a number less then 9

Explanation:

We know its not 7

because 7 + 2 < 9 = 9 = 9

we want something that is less then 9

1 up to 7 would give you an answer less then 9

6 + 2< 9 = 8 < 9

5 + 2 < 9 = 7 < 9

4 + 2 < 9 = 6 < 9

and more

Answer 2
