Part A: Connor is wrong, this is because the inequality 9x<27 means that 9x is LESS than 27. For example, if x was 17, it would mean 9 times 17 (153) which is WAAAY more than 27. Connor's statement is nonsense.
Part B: x could equal 2 or less. This is because anything over 2 will not fit with the inequality. (if x was 3 that would make it equal to 27 and that won't be right). 9 times 2 is 18 which is less than 27, so is 1 and so on :)
