All u have to do is find what variable will make each statement true, I'll do one so u would get what I mean,
61. x + 13.5 < 19, this could be anything under 19 since it's supposed to be greater, I chose 5 + 13.5 < 19 which is 18.5 < 19
The number goes from 13.5 to 19 you could do it like decimals, start it from 13 then go on like this, 13,13.5,14,14.5,15,15.5,16,16.5,17,17.5,18,18.5,& 19.
