A - Difference in tides for location C is 6.9 feet and high tide for location A is 8.2 feet.
B - Value of low tide in location D is -0.64 feet.
The table showing the difference between high and low tides.
The difference in tides for location C = 7.34 - 0.44 = 6.9
We are given, the mean of the low tides for the 4 locations is -0.54
The amount saved by Rita is $25.
Given that, the skateboard Rita wants to buy is 6 dollars less than 3 times the amount she has saved. The skateboard is 69 dollars.
<h3>What is an equation?</h3>
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the unknown number be x.
Now, 3x-6=69
⇒ 3x=75
⇒ x=75/3
⇒ x= 25
Therefore, the amount saved by Rita is $25.

The skateboard Rita wants to buy is 6 dollars less than 3 times the amount she has saved. The skateboard is 69 dollars. How much has Rita saved.
300 must be subtracted from the product of 25 and 23 to equal 275.
Answer:
15 < n < 25
Step-by-step explanation:
According to the triangle inequality theorem, any two sides lengths' sum should be greater than the third side. This also implies that to find the <em>possible length of the 3rd side given other two sides (let two given sides be x and y)</em>, we can say that the 3rd side length will be between x+y and x-y.
Hence, we can say that <em><u>n should be between 20+5 and 20-5</u></em>.
So, 20 - 5 < n < 20 + 5, which is
15 < n < 25
<em>This is the correct answer.</em>
