To find the change in temperature during these three hours, we need to subtract the initial air temperature from the final air temperature.
The initial air temperature at 9 a.m. is -5.8 degrees Celsius.
The final air temperature at noon is -1.6 degrees Celsius.
Change in temperature = final temperature - initial temperature
Change in temperature = (-1.6°C) - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
The initial air temperature at 9 a.m. is -5.8 degrees Celsius.
The final air temperature at noon is -1.6 degrees Celsius.
Change in temperature = final temperature - initial temperature
Change in temperature = (-1.6°C) - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.

Apologies for the incorrect calculation. Let's recalculate the change in temperature:
Change in temperature = final temperature - initial temperature
Change in temperature = -1.6°C - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.
Change in temperature = final temperature - initial temperature
Change in temperature = -1.6°C - (-5.8°C)
Change in temperature = -1.6°C + 5.8°C
Change in temperature = 4.2°C
Therefore, the change in temperature during these three hours is 4.2 degrees Celsius.

To add -12 and -15, we simply add their values:
-12 + (-15) = -27.
Therefore, -12 + (-15) = -27.
-12 + (-15) = -27.
Therefore, -12 + (-15) = -27.

To add 10.82 and -15.96, simply add their values:
10.82 + (-15.96) = -5.14.
Therefore, 10.82 + (-15.96) = -5.14.
10.82 + (-15.96) = -5.14.
Therefore, 10.82 + (-15.96) = -5.14.

To find the temperature now, we need to subtract the change in temperature from the initial temperature.
Initial temperature = 13°C
Change in temperature = -18.6°C
Temperature now = Initial temperature + Change in temperature
Temperature now = 13°C + (-18.6°C)
Temperature now = -5.6°C
Therefore, the temperature now is -5.6 degrees Celsius.
Initial temperature = 13°C
Change in temperature = -18.6°C
Temperature now = Initial temperature + Change in temperature
Temperature now = 13°C + (-18.6°C)
Temperature now = -5.6°C
Therefore, the temperature now is -5.6 degrees Celsius.

To find -492.89 - (-871.78), we can use the additive inverse of the second number and change the subtraction into addition:
-492.89 + 871.78 = 378.89
Therefore, -492.89 - (-871.78) = 378.89.
-492.89 + 871.78 = 378.89
Therefore, -492.89 - (-871.78) = 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we subtract the smaller number from the larger number:
|-18.26 - (-2.45)| = |-18.26 + 2.45|
|-18.26 + 2.45| = |-15.81|
The absolute value of -15.81 is 15.81.
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81 units.
|-18.26 - (-2.45)| = |-18.26 + 2.45|
|-18.26 + 2.45| = |-15.81|
The absolute value of -15.81 is 15.81.
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81 units.

First, let's solve the absolute value expression within the problem.
|1/3 * -9| = |-3| = 3
Now we can substitute this value back into the original problem and solve further:
2 - 3 - 5 = -6
Therefore, 2 - |1/3 * -9| - 5 = -6.
|1/3 * -9| = |-3| = 3
Now we can substitute this value back into the original problem and solve further:
2 - 3 - 5 = -6
Therefore, 2 - |1/3 * -9| - 5 = -6.

To solve 17 4/9 + 5/9 - 8 - 10, we first need to convert the mixed number to an improper fraction:
17 4/9 = (9 * 17 + 4)/9 = 153/9
Now we can simplify the expression:
(153/9) + (5/9) - 8 - 10 = (153 + 5)/9 - 8 - 10 = 158/9 - 8 - 10
To subtract fractions, we need a common denominator:
158/9 - 8 = 158/9 - (8 * 9)/9 = 158/9 - 72/9 = (158 - 72)/9 = 86/9
Now we can simplify further:
86/9 - 10 = 86/9 - (10 * 9)/9 = 86/9 - 90/9 = (86 - 90)/9 = -4/9
Therefore, 17 4/9 + 5/9 - 8 - 10 = -4/9.
17 4/9 = (9 * 17 + 4)/9 = 153/9
Now we can simplify the expression:
(153/9) + (5/9) - 8 - 10 = (153 + 5)/9 - 8 - 10 = 158/9 - 8 - 10
To subtract fractions, we need a common denominator:
158/9 - 8 = 158/9 - (8 * 9)/9 = 158/9 - 72/9 = (158 - 72)/9 = 86/9
Now we can simplify further:
86/9 - 10 = 86/9 - (10 * 9)/9 = 86/9 - 90/9 = (86 - 90)/9 = -4/9
Therefore, 17 4/9 + 5/9 - 8 - 10 = -4/9.

To find how far Joey was from home, we need to subtract the distance he walked west from the distance he walked east.
Distance walked east = 15 2/3 meters
Distance walked west = 21 3/4 meters
First, we need to convert the mixed numbers to improper fractions:
15 2/3 = (3 * 15 + 2)/3 = 47/3 meters
21 3/4 = (4 * 21 + 3)/4 = 87/4 meters
Now, we can subtract the distance walked west from the distance walked east:
47/3 - 87/4
To subtract fractions, we need a common denominator of 12:
(47/3) * (4/4) - (87/4) * (3/3) = 188/12 - 261/12 = -73/12
Therefore, Joey is 73/12 meters away from home.
