It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now
To find the temperature now, we need to calculate 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.
Use the additive inverse to find −492.89−(−871.78
To find the value of "-492.89 - (-871.78)", we can use the additive inverse property.
The additive inverse of a number is the number that, when added to the original number, results in zero. To find the additive inverse of a number, we simply change its sign.
So, the additive inverse of (-871.78) is 871.78.
Now, we can rewrite the expression as:
-492.89 + 871.78
Adding these numbers, we get:
-492.89 + 871.78 = 378.89
Therefore, -492.89 - (-871.78) equals 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 and take the absolute value.
|-2.45 - (-18.26)| = |-2.45 + 18.26| = |15.81| = 15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
Solve the mathematical problem involving absolute value.
2−|13⋅−9|−5
To solve the expression 2 - |13*(-9)| - 5, we first evaluate the absolute value:
|13*(-9)| = |-117| = 117
Now we can substitute the absolute value back into the expression:
2 - 117 - 5
Next, we perform the subtraction:
2 - 117 - 5 = -120
Therefore, the solution to the expression 2 - |13*(-9)| - 5 is -120.
Subtract 24−(−15)
To subtract 24 - (-15), we can rewrite the expression as:
24 + 15
Now, we can add the numbers:
24 + 15 = 39
Therefore, 24 - (-15) equals 39.

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

To find the value of the expression 17 4/9 + 5/9 - 8 - 10, we first need to simplify the mixed numbers by converting them to improper fractions:
17 4/9 = (9 * 17 + 4)/9 = 153/9
8 = 8/1
10 = 10/1
Now we can rewrite the expression:
(153/9) + (5/9) - (8/1) - (10/1)
Next, we need to find a common denominator for the fractions, which is 9 in this case:
(153/9) + (5/9) - (72/9) - (90/9)
Now we can add and subtract the fractions:
(153 + 5 - 72 - 90)/9 = (-4)/9
Therefore, the value of 17 4/9 + 5/9 - 8 - 10 is -4/9.

To find the value of the expression 17 4/9 + 5/9 − 8 − 10, we first need to simplify the mixed number 17 4/9 by converting it to an improper fraction:
17 4/9 = (9 × 17 + 4)/9 = 153/9
Now we can rewrite the expression:
(153/9) + (5/9) - 8 - 10
Next, we can combine like terms:
(153/9 + 5/9) - 18
To add the fractions with the same denominator:
(153 + 5)/9 - 18
158/9 - 18
Now, to subtract the fractions:
(158 - (18 × 9))/9
(158 - 162)/9
-4/9
Therefore, the value of 17 4/9 + 5/9 - 8 - 10 is -4/9.
