Temperature at 9 a.m.: -5.8 degrees Celsius

Question

Temperature at noon: -1.6 degrees Celsius

Change in temperature = Temperature at noon - Temperature at 9 a.m.

Change in temperature = -1.6 - (-5.8)

To subtract a negative number, we can rewrite the expression as an addition:

Change in temperature = -1.6 + 5.8

Change in temperature = 4.2 degrees Celsius

The equation and solution show that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon. This means that the air temperature became warmer

Answer 1

Sure! Let's look at the temperature change step by step.

1. Initial Temperatures:

   • At 9 a.m., the temperature is -5.8 degrees Celsius.
   • At noon, the temperature is -1.6 degrees Celsius.

2. Finding Change in Temperature:

   • To find out how much the temperature changed, we will subtract the morning temperature from the afternoon temperature.
   • The formula is:
     Change in temperature = Temperature at noon - Temperature at 9 a.m.

   Plugging in the numbers:
   Change in temperature = -1.6 - (-5.8)

3. Subtracting a Negative:

   • Subtracting a negative number is the same as adding. So, we can rewrite this as:
     Change in temperature = -1.6 + 5.8

4. Doing the Math:

   • Now, let's add those two numbers:
     -1.6 + 5.8.
   • When we do the addition, we get 4.2 degrees Celsius.

5. Final Answer:

   • This means the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon. So, the air got warmer!

In summary, the temperature went up by 4.2 degrees Celsius, making it a bit more comfortable as the day went on!

Answer 2

can you simplify the answer a little more?

Answer 3

Sure! Here’s a simpler version:

1. Temperatures:

   • At 9 a.m., it’s -5.8 degrees Celsius.
   • At noon, it’s -1.6 degrees Celsius.

2. Finding the Change:

   • To find out how much warmer it got, we do this calculation:
     Change in temperature = Temperature at noon - Temperature at 9 a.m.
     So, we write it like this:
     Change in temperature = -1.6 - (-5.8).

3. Adding Instead of Subtracting:

   • Remember, subtracting a negative number means you add. So we flip it:
     Change in temperature = -1.6 + 5.8.

4. Calculating:

   • Now, we simply add:
     -1.6 + 5.8 = 4.2.

5. Conclusion:

   • The temperature went up by 4.2 degrees Celsius. This means it got warmer from the morning to noon!

So, in short: The air temperature increased by 4.2 degrees Celsius!
