Question

let#x represent the greatest even number less than x. if 20 13 years ago

Answer 1

hmm is it 28 ?

Answer 2

i can't see how you can make it larger than 28 but maybe i am missing something

Answer 3

I agree with @satellite73 .
My reasoning goes like this: x is at most 29, so #x is at most 28. So #5x - #4x = 28.

Answer 4

Unless by #4x it means #4x, not 4(#x)?

Answer 5

Well...I guess the answer would be the same either way.

Answer 6

is 30

Answer 7

@lalaio how is it 30? How did you get 30?
