Question

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses whenever possible.

Answer 1

Answer:

The sum is $t$.

Step-by-step 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 $t$.
