A) 11.

Step-by-step explanation:

x - 9 > 3 Add 9 to both sides:

x > 3 + 9

x > 12.

The only number in the list that is not greater than 12 is 11.

Gideon Benton · Answer 2

A

Step-by-step explanation:

x > 12

13, 15 and 17 are all greater than 12

However, 11 is less than 12 and is not in the solution set → A
