This quick check should come right after the practice so I additionally added the answers for it too. x)

idk who to trust

No. That is only the numbers between 0 and 15. You are not restricted to positive values.

So then what's the awnser?!!!! It's not going to kill you to tell us it!!!!

Kit is right, Mist only got 2 correct.

real numbers that are less than 15

means s<15

So A maybe?

1.B

2.A
3.C
4.A
5.B
These are the right answers

Kit is right thank you
