Use the additive inverse to find −492.89−(−871.78).(1 point)
Bot GPT 3.5
answered
To find the value of −492.89−(−871.78), we can use the additive inverse.
−492.89 − (−871.78) is equivalent to −492.89 + 871.78.
Therefore, −492.89 − (−871.78) = 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we can subtract the two values and take the absolute value.
|-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.

Solve the mathematical problem involving absolute value.
2−|13⋅−9|−5(1 point)
Bot GPT 3.5
answered
First, we calculate the absolute value of 13⋅−9:
|13⋅−9| = |-117| = 117
Now, we can substitute this value into the equation:
2 - |13⋅-9| - 5 = 2 - 117 - 5 = -120
Therefore, the solution to the equation 2−|13⋅−9|−5 is -120.

To solve the problem 17 4/9 + 5/9 − 8 − 10, we need to convert the mixed numbers to improper fractions in order to perform the addition and subtraction.
17 4/9 can be rewritten as (9 * 17 + 4)/9 = (153 + 4)/9 = 157/9.
Now we can perform the calculation:
157/9 + 5/9 - 8 - 10 = (157 + 5)/9 - 8 - 10 = 162/9 - 18 = 18 - 18 = 0.
Therefore, the result of 17 4/9 + 5/9 − 8 − 10 is 0.

Joey walked east for 1523 meters from home. Then, he walked west for 2134 meters. How far was Joey from home?(1 point)
Bot GPT 3.5
answered
To determine how far Joey is from home, we need to calculate the net distance by subtracting the distance walked west from the distance walked east.
1523 meters (east) - 2134 meters (west) = -611 meters
Therefore, Joey is 611 meters from home in the west direction.

Solve the following word problem. The air temperature at 9 a.m. is −5.8 degrees Celsius. The air temperature at noon is −1.6 degrees Celsius. What is the change in the temperature during these three hours? Write and solve an equation to show your answer. Then explain what your answer means.(4 points)
Bot GPT 3.5
answered
To find the change in temperature during these three hours, we need to 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)
Simplifying, we have:
Change in temperature = -1.6°C + 5.8°C
Change in temperature = 4.2°C
The change in temperature during these three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius from 9 a.m. to noon.
