you should explain how you arrive at that conclusion.

for 6: notice that out of 3 consecutive integers, one is a multiple of 3.

Ex. 4 has three different parts. On which one are you saying the answer is the empty set?

on (1.). Theres is no ||x|| that is smaller then 0.5 because any number you will choose to put in the |t| and 't' it will give you the rest, like 0.6 and 0.4 , (0.6 max) the highest you will get is 0.5 , no matter what

baisclly I have done 4, and 5 , 6 is hard but I have some explanation writing by other student, I dunno if its correct but I think it is

7 is kinda hard work but can be done

I need help with 8. and there are 9,10,11,12,13 , I will upload now and that will be it, any help will be appriciated
