Question

At 6am the temperature was 45 degrees Celsius, then dropped 50 degrees by the end of the day.Write an addition equation to find the final temperature.

Answer 1

To calculate the final temperature after a drop of 50 degrees Celsius from 45 degrees Celsius, use the addition equation T final = 45 °C + (-50 °C) to get a final temperature of -5 °C.

Step-by-step explanation:

To find the final temperature after a drop of 50 degrees Celsius from an initial temperature of 45 degrees Celsius, we can set up an addition equation. We denote the initial temperature as Tinitial and the change in temperature as ΔT.

Here's how you can express it:
Tfinal = Tinitial + (ΔT), where ΔT is negative because the temperature is dropping.

Substituting the values we get: Tfinal = 45 °C + (-50 °C) = -5 °C.

So, the final temperature is -5 °C by the end of the day after dropping 50 degrees Celsius from the initial 45 degrees Celsius.
