Question
Find the sum of p and q if p=34 and q=−114. Reduce your answer to lowest terms.(1 point)
To find the sum of p and q, we add the values of p and q together.
p = 34
q = -114
p + q = 34 + (-114) = -80
Therefore, the sum of p and q, reduced to lowest terms, is -80.

Question
Solve the following problem:
It was 13°C yesterday, but the temperature changed by −18.6° overnight. What is the temperature now?(1 point)
°C
To find the temperature now, we need to subtract the change in temperature from the temperature yesterday.
Temperature yesterday: 13°C
Change in temperature: -18.6°
Temperature now = Temperature yesterday + Change in temperature
Temperature now = 13°C + (-18.6°) = -5.6°C
Therefore, the temperature now is -5.6°C.
Use the additive inverse to find −492.89−(−871.78).(1 point)
To find the value of −492.89−(−871.78), we can rewrite it as −492.89 + 871.78 using the additive inverse.
−492.89 + 871.78 = 378.89
Therefore, the value of −492.89−(−871.78) is 378.89.

To determine the distance between -18.26 and -2.45 on a number line, we subtract the two numbers and take the absolute value.
|-18.26 - (-2.45)| = |-18.26 + 2.45|
Next, we add the two numbers:
|-15.81|
Taking the absolute value, we have:
15.81
Therefore, the distance between -18.26 and -2.45 on a number line is 15.81.
Subtract 24−(−15)
To subtract 24 - (-15), we can rewrite it as 24 + 15 using the additive inverse.

To solve the expression 1749 + 59 - 8 - 10, we perform the calculations according to the order of operations (parentheses, exponents, multiplication and division from left to right, and addition and subtraction from left to right).
1749 + 59 - 8 - 10 = 1808 - 18 = 1790
Therefore, the result of the expression is 1790.

To solve the expression 17 4/9 + 59 - 8 - 10, we first need to convert the mixed number 17 4/9 to an improper fraction.
17 4/9 = (17 * 9 + 4)/9 = 153/9
Now we can perform the calculations:
153/9 + 59 - 8 - 10 = 153/9 + 59 - 18 = 153/9 + 41 = (153 + 9 * 41)/9 = (153 + 369)/9 = 522/9 = 58
Therefore, the result of the expression is 58.

Question
Joey walked east for 15 2/3 meters from home. Then, he walked west for 21 3/4 meters. How far was Joey from home?(1 point)
Joey was
meters from home.
To determine how far Joey was from home, we can 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
To subtract these distances, we need to find a common denominator.
15 2/3 = (3 * 15 + 2)/3 = 47/3
21 3/4 = (4 * 21 + 3)/4 = 87/4
Now we can subtract:
47/3 - 87/4 = (4 * 47 - 3 * 87)/(3 * 4) = (188 - 261)/12 = -73/12
Therefore, Joey was -73/12 meters from home.
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)
To find the change in temperature during the three hours from 9 a.m. to noon, we subtract the starting temperature from the ending temperature:
Change in temperature = Ending temperature - Starting temperature
Starting temperature = -5.8 degrees Celsius
Ending temperature = -1.6 degrees Celsius
Change in temperature = (-1.6) - (-5.8)
Change in temperature = -1.6 + 5.8
Change in temperature = 4.2
Therefore, 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.
