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.

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

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer
