Answer:30° - 3d ≤ 20°
Step-by-step explanation:
We have to represent the rate of temperature decrease in degrees .We will represent this by "d" which stands for degree.
According to the question , temperature decreased at a constant rate in the next three days
Therefore , the total decreasing in three days = 3d degree i.e 3 *d=3d
Temperature on Monday = 30°
Then the temperature on Thursday is this = 30° - 3d
Since, The swimming pool is open when the high temperature is higher than 20°=≤20
= 30° - 3d ≤ 20°
This is the required inequality to determine the rate of temperature decrease in degrees Celsius per day, "d"from Monday to Thursday.

there is more than one answer but this is the one i came up with lol
14 you are adding 3 to each number
The value of the 6 is 3.
If you write 1 in word then you will write one and if you count the letter it will give you 3
Similarly, if you write the numbers 2,3,4,5 in word and count the number you will get 3,5,4,4 respectively.
<h3>What are the counting letters?</h3>
counting Letters provides a perfect way to introduce number words to beginning readers, as well as discuss the concepts of letters and words.
So, if you write 6 in words you will write six and on counting the letter you will get 3.
Hence, 6 = 3 ans.
Therefore the value of the 6 is 3.
