Answer:
-90 - (-144)
Step-by-step explanation:
Here you go!
Since we're depositing, you'll add the three numbers.
45 + 27 + 18 = $90
Cody deposits 90 dollars in total.
If you write checks, the numbers go down. So you'll add them, and then subtract that by the 90 dollars Cody deposits.
You'll end up with:
45 + 27 + 18 - (21 + 93)
This can simplify to..
90 - (21 + 93)
But wait! Let's add what's in the parenthesis!
93 + 21 = 144
90 - 144 = t
t = -54
Solving this equation will give you: -54
But the simple way is -90 - (-144)

<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.
