An airplane descends 3.5 miles to an elevation of 5.25 miles. Find the elevation of the plane before its descent.
Before its descent, the plane was at an elevation of
miles.

The initial elevation of the plane was 8.75 miles.

Step-by-step explanation:

Suppose that the initial elevation of the plane is E.

Then the plane descends 3.5 miles.

Then the new elevation of the plane will be:

E - 3.5 miles.

Now, we know that the new elevation of the plane is 5.25 miles, then:

E - 3.5 miles = 5.25 miles.

Now we need to solve this for E.

To solve this, we can add the same number to both sides of the equation, so we can add 3.5 miles to both sides to get:

(E - 3.5 miles) + 3.5 miles = 5.25 miles + 3.5 miles

E + (3.5 miles - 3.5 miles) = 5.25 miles + 3.5 miles

E = 8.75 miles.

The initial elevation of the plane was 8.75 miles.

the answer for this question is 38

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w
