- 4. Reduce your answer to lowest terms. (1 point)
I'm sorry, but the given information is incomplete. Could you please provide the values of p and q?
Find the sum of p and q if p = 3/4 and q = - 11/4 Reduce your answer to lowest terms. (1 point)
To find the sum of p and q, we simply add the fractions:
p + q = 3/4 + (-11/4)
When adding fractions, we need to have a common denominator. In this case, the common denominator is 4. Therefore, we can rewrite the fractions with the common denominator:
p + q = 3/4 - 11/4
Now, we can combine the numerators:
p + q = (3 - 11)/4 = -8/4
Next, we can reduce the fraction to lowest terms by dividing the numerator and denominator by their greatest common divisor, which in this case is 4:
p + q = -8/4 = (-8/4) / (4/4) = -2/1 = -2
Therefore, the sum of p and q is -2.
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, we can subtract the initial temperature from the final temperature.
Change in temperature = Final temperature - Initial temperature
In this case, the initial temperature at 9 a.m. is -5.8 degrees Celsius and the final temperature at noon is -1.6 degrees Celsius.
Change in temperature = -1.6 - (-5.8)
= -1.6 + 5.8
= 4.2
The change in temperature during these three hours is 4.2 degrees Celsius.
This means that the temperature increased by 4.2 degrees Celsius between 9 a.m. and noon.
