Which expressions simplify to 0? Check all that apply. 8g – 8g, (–2g) – 2g, 5g + (–5g), One-half g + one-half, g Negative two-thirds g + two-thirds g

We have been given 4 expressions. We are asked to choose the expressions, which simplifies to 0.

Let us check our given choices one by one.

1.

When we will subtract 8g from 8g, we will get 0. Therefore, expression simplifies to 0.

2.

Let us remove parenthesis.

Upon combining like terms, we will get:

Since   simplifies to , therefore, expression is not a correct choice.

3.

Let us remove parenthesis.

Upon combining terms, we will get:

Since   simplifies to 0, therefore, expression   is a correct choice.

4.

Let us combine the terms as:

Since simplifies to , therefore, expression is not a correct choice.

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
