It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".

Nine less than three times a number; the initial number being represented by s.
Depending on where the parentheses are supposed to go, it could be (-4p) or it could be (5p - 9) .
9(m-cubed)+(m-squared)
(x + 9)
9x
I'm pretty sure they use that expression because a cat they say has nine lives, but I can't be sure.

It could be: -3/8+4x-9z as an algebraic expression
Nine less than three times a number; the initial number being represented by s.
Depending on where the parentheses are supposed to go, it could be (-4p) or it could be (5p - 9) .
If you want to say "Nine is less than a number k," you would write 9<K. If you're asking for an equation, e.g. "Nine less than a number k is equal to that number divided by three," you would write k - 9.
