Which number is the additive inverse of -5?
Marysya12 [62]

Answer:

It would be 5

Step-by-step explanation:

SO the additive inverse would basically just be the opposite of the number, for example lets say you had 12, the additive inverse would be -12. You're just changing the sign of the number! From what i know i believe that's it. Have a nice day! :D
