d. The opposite of - 10t and t - 10t

Answer 1

The sum is
`t`.

Explanation:

Consider the provided information.

The given expression are - 10t and t - 10t

We need to find the sum of the opposite of -10 t and t - 10t.

The opposite of -10 t is 10 t.

`10t+(t-10t)`

Remove the parenthesis.

`10t+t-10t`

Simplify the number

`10t-10t+t`

Use Additive inverse.

`t`

Hence, the sum is
`t`.
