degree every
hour for a limited time.
To find : What was the rate, in degrees per hour that the temperature of the compound rose ?

degree
degree/hr
degree/hr
Therefore, the rate is
degree per hour.
We could write the fractions as decimals.

The answer is
.004 or 4/1000.
Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
