Find the sum of p and q if p = 3/4 and q =−11/4. Reduce your answer to lowest terms.
_______
To find the sum of p and q, we add their values together:
p + q = 3/4 + (-11/4)
To add fractions, we need to have a common denominator. The common denominator of 4 and 4 is 4.
p + q = (3 - 11)/4
Now we can subtract the numerators:
p + q = -8/4
The fraction -8/4 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4:
p + q = -2/1
Therefore, the sum of p and q is -2.

To find the sum of -12 and -15, we add their values together:
(-12) + (-15) = -27
Therefore, the sum of -12 and -15 is -27.
Add 10.82+(−15.96).(1 point)
To add 10.82 and -15.96, we simply add their values together:
10.82 + (-15.96) = -5.14
Therefore, the sum of 10.82 and -15.96 is -5.14.
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 current temperature, we need to subtract the change in temperature from the initial temperature:
13°C + (-18.6°C) = -5.6°C
Therefore, the current temperature is -5.6°C.
Use the additive inverse to find −492.89 − (−871.78).(1 point)
_____
To find the subtraction of -492.89 and -871.78, we can use the additive inverse.
−492.89 − (−871.78) is equivalent to −492.89 + 871.78.
Now, we can add the values together:
−492.89 + 871.78 = 378.89.
Therefore, −492.89 − (−871.78) is equal to 378.89.
