Question

six is added to, the sum of fifteen and the additive inverse of twenty​

Answer 1

Answer:

1.

Step-by-step explanation:

First it is said that 6 is added to the sum of 15 and additive inverse of 20.

Now for finding sum of 15 and additive inverse of 20, we should first know what is the additive inverse of any number(here, 20).

The additive inverse of any number is the the number with the opposite sign.

For eg., the additive inverse of 1 is  -1 and the additive inverse of -57 is +57.

So additive inverse of 20 = -20.

Now sum of 15 and - 20 = 15 + (-20)

= 15 - 20 = -5.

Now 6 is added to -5 + 6  = 1.

So the solution is 1.
