Amile is 5,280 feet between which two integers is the elevation of the trench in miles-21,844 feet is between and miles

21,844 feet is between 4 and 5 miles.

Step-by-step explanation:

We are asked to find two integers between which the elevation of the 21,844 feet trench lies in miles.

Let us convert 21,844 feet into miles by dividing 21,844 by 5,280 as 1 mile equals 5,280 feet.

We can see that 21,844 feet is equal to 4.137 miles, which is greater than 4 miles and less than 5 miles, therefore, 21,844 feet is between 4 and 5 miles.

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
