Question

It's was 55°F outside until the temperature increased 20°F. Which number is the additive inverse of the temperature increase? A) −20 B) −55 C) 20 D) 55

Answer 1

Answer:

Option A)  -20°F.

Step-by-step explanation:

Given : It's was 55°F outside until the temperature increased 20°F.

To find : Which number is the additive inverse of the temperature increase?

Solution :

Additive inverse is defined as,

For any number 'a', the additive inverse is $a+(-a)=0$ or $-1\cdot a=-a$

According to question,

The temperature is increased 20°F.

To follow the additive inverse property,

The sum became zero.

So, Additive inverse is -20°F.

Therefore, Option A is correct.

The additive inverse of the temperature increase is  -20°F.

Answer 2

A) -20

Hope its correct good-luck (sorry im so late)
