You need to add 5d with 5d then add the d to it for it to get the length and the width
We have (1,4) + (-1,-4) = (0,0), because 1 + (-1) = 1 - 1 = 0 and 4 + (-4) = 4 - 4 = 0.
Step-by-step explanation:
Rational numbers are numbers that terminate or are a repeating decimal.
4 rational numbers between -1/3 and -1/2 are
-5/12,
-0.583333333333333333333333333...,
-0.54166666666666..., and
-0.5208333333...
<u>Answer:</u>
The temperature change per hour was -3 degrees per hour.
<u>Step-by-step explanation:</u>
We know that the temperature fell from
degrees to
degrees in a time period of
hours.
So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.
For that, we will change the mixed number into improper fractions and then solve:

Temperature change per hour = 
Therefore, the temperature change per hour was -3 degrees per hour.
