"Nine times a number" translates to 9x and "decreased by 29" translates to -29, so the expression is 9x - 29. This cannot be simplified further. "Nine times a number" can be written as 9x, and "decreased by 29" means subtracting 29. Therefore, the expression is 9x - 29. This cannot be simplified further.
