Question

Brand 1 of antifreeze clalms that it can withstand temperatures of -62°C. Brand 2 of antreeze claims that it can withstand temperatures 5°C below those of Brand 1. Which equation represents the temperatures Brand 2 can withstand? A. -62 + 5 = -57 B. -62 + 5 = -67C. +62 + (-5) = -67 -D. 62 + (-5) = -57

Answer 1

-62 + (-5) = -67

Step-by-step explanation:

If we need to find a temperature that is 5°C below, we need to subtract 5°C from the initial temperature.

For example, 5°C below 15°C is equal to:

15°C - 5°C = 10°C

If the initial temperature is -62°C, 5°C below is calculated as:

-62°C - 5°C

Since both numbers have a negative sign, we need to add the numbers and the result will also be negative.

It can also be written as:

-62 + (-5) = -67

It means that -67°C is 5°C below -62°C
