20 1/3 + x = - 9 round your answer to the nearest hundredth

I would think it's X = - 29 1/3

Step-by-step explanation:

You have 20 1/3 already, and to get to a negative when you have a positive number, to the positive you would need to add a larger negative. (If that makes any sense, it's hard to explain.) So you have to get rid of the 20 1/3 and you have to get to - 9, so I would add a 9 to 20 1/3 to get 29 1/3, and make that number negative because then it will cancel the positive out. Making it - 9.
