Question

An airplane descends 1.6 miles to an elevation of 6.95 miles. Find the elevation of the plane before its

descent.
The initial elevation of the plane was
Smiles.

Answer 1

Step-by-step explanation: First, let's call the starting elevation of the plane: e

We can then write an equation representing this problem as:

e−1.5mi=5.25mi

Now, add 1.5mi to each side of the equation to solve for e

while keeping the equation balanced:

e−1.5mi + 1.5mi=5.25mi + 1.5mi

e−0=6.75mi

e=6.75mi

The plane's starting elevation was 6.75 miles
