The sum of p and q, when p = 34 and q = -114, is equal to:
p + q = 34 + (-114) = -80
So, the sum of p and q, in lowest terms, is -80.
p + q = 34 + (-114) = -80
So, the sum of p and q, in lowest terms, is -80.

To find the temperature now, we need to find the sum of the initial temperature and the change in temperature:
13°C + (-18.6°C) = -5.6°C
Therefore, the temperature now is -5.6°C.
13°C + (-18.6°C) = -5.6°C
Therefore, the temperature now is -5.6°C.

To find the difference between -492.89 and -871.78, we can use the additive inverse. The additive inverse of -871.78 is 871.78 (changing the sign). So, the problem becomes:
-492.89 + 871.78 = 378.89
Therefore, the expression -492.89 - (-871.78) is equal to 378.89.
-492.89 + 871.78 = 378.89
Therefore, the expression -492.89 - (-871.78) is equal to 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we calculate the absolute difference between the two numbers:
|-18.26 - (-2.45)| = |-18.26 + 2.45| = |-15.81| = 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| = |-15.81| = 15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81 units.

To find the value of the expression 1749 + 59 - 8 - 10, we perform the addition and subtraction operations from left to right:
1749 + 59 = 1808
1808 - 8 = 1800
1800 - 10 = 1790
Therefore, the value of the expression 1749 + 59 - 8 - 10 is 1790.
1749 + 59 = 1808
1808 - 8 = 1800
1800 - 10 = 1790
Therefore, the value of the expression 1749 + 59 - 8 - 10 is 1790.

To find the value of the expression 17 4/9 + 59 - 8 - 10, we perform the addition and subtraction operations from left to right:
First, we convert the mixed number 17 4/9 to an improper fraction:
17 4/9 = (9 * 17 + 4) / 9 = 157/9
Now, we can calculate the expression:
157/9 + 59 = (157 + 9 * 59) / 9 = (157 + 531) / 9 = 688 / 9
To simplify further, we can express 688 as a mixed number:
688 / 9 = 76 4/9
Finally, we perform the remaining subtractions:
76 4/9 - 8 = 76 - 8 + 4/9 = 68 + 4/9 = 68 4/9
68 4/9 - 10 = 68 - 10 + 4/9 = 58 + 4/9 = 58 4/9
Therefore, the value of the expression 17 4/9 + 59 - 8 - 10 is 58 4/9.
First, we convert the mixed number 17 4/9 to an improper fraction:
17 4/9 = (9 * 17 + 4) / 9 = 157/9
Now, we can calculate the expression:
157/9 + 59 = (157 + 9 * 59) / 9 = (157 + 531) / 9 = 688 / 9
To simplify further, we can express 688 as a mixed number:
688 / 9 = 76 4/9
Finally, we perform the remaining subtractions:
76 4/9 - 8 = 76 - 8 + 4/9 = 68 + 4/9 = 68 4/9
68 4/9 - 10 = 68 - 10 + 4/9 = 58 + 4/9 = 58 4/9
Therefore, the value of the expression 17 4/9 + 59 - 8 - 10 is 58 4/9.

To find how far Joey was from home, we need to calculate the absolute difference between the distances he walked east and west:
1523 meters - 2134 meters = -611 meters
Since Joey walked west after walking east, the distance is negative. To find the absolute value, we take the positive value of -611 meters:
|-611 meters| = 611 meters
Therefore, Joey was 611 meters from home.
1523 meters - 2134 meters = -611 meters
Since Joey walked west after walking east, the distance is negative. To find the absolute value, we take the positive value of -611 meters:
|-611 meters| = 611 meters
Therefore, Joey was 611 meters from home.

To find the change in temperature during the three hours from 9 a.m. to noon, we can subtract the temperature at 9 a.m. from the temperature at noon:
Change in Temperature = Temperature at Noon - Temperature at 9 a.m.
Change in Temperature = (-1.6°C) - (-5.8°C)
Change in Temperature = -1.6°C + 5.8°C
Change in Temperature = 4.2°C
So, the change in temperature during the three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
Change in Temperature = Temperature at Noon - Temperature at 9 a.m.
Change in Temperature = (-1.6°C) - (-5.8°C)
Change in Temperature = -1.6°C + 5.8°C
Change in Temperature = 4.2°C
So, the change in temperature during the three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.

To solve the expression 17 4/9 + 5/9 - 8 - 10, we first convert the mixed number 17 4/9 to an improper fraction:
17 4/9 = (9 * 17 + 4)/9 = 157/9
Now we substitute the values into the expression and perform the operations:
(157/9) + (5/9) - 8 - 10 = (157/9 + 5/9) - 8 - 10 = (162/9) - 8 - 10
Next, we simplify the expression:
(162/9) - 8 - 10 = (162 - 72 - 90)/9 = 0/9 = 0
Therefore, the value of the expression 17 4/9 + 5/9 - 8 - 10 is 0.
17 4/9 = (9 * 17 + 4)/9 = 157/9
Now we substitute the values into the expression and perform the operations:
(157/9) + (5/9) - 8 - 10 = (157/9 + 5/9) - 8 - 10 = (162/9) - 8 - 10
Next, we simplify the expression:
(162/9) - 8 - 10 = (162 - 72 - 90)/9 = 0/9 = 0
Therefore, the value of the expression 17 4/9 + 5/9 - 8 - 10 is 0.
