Question

What is the additive inverse of -7?-761/77

Answer 1

The additive inverse of a number is another number that, when added to the initial number, the result is equal to 0.

The additive inverse is also known as the opposite of a number.

Let's use the variable x to represent the additive inverse of -7.

So, we can write the following equation and solve it for x:

`\begin{gathered} -7+x=0 \\ -7=-x \\ 7=x\to x=7 \end{gathered}`

Therefore the additive inverse of -7 is equal to 7, and the correct option is the fourth one.
