Answer:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Step by step explanation:
Let d represent the rate of temperature decrease in degrees Celsius per day from Monday to Thursday.
As temperature decreased at a constant rate in the next 3 days, so the rate of temperature will decrease 3d degree Celsius in 3 days.
We are told that the pool was open on Monday. The high temperature was
on Monday. So the decrease in temperature from Monday to Thursday will be
.
We have been given that the swimming pool is open when the high temperature is higher than
.
As the pool was closed on Thursday. This means that temperature on Thursday was less than or equal to 20 degree Celsius. We can represent this information in an inequality as:
![30-3d\leq 20](https://tex.z-dn.net/?f=30-3d%5Cleq%2020)
Therefore, the inequality
can be used to determine the rate of temperature decrease in degrees Celsius per day, d, from Monday to Thursday.
I believe the correct answer here would be C. x=10/3 because it is the only proportional answer.
Answer:
