Answer:

A.The elevation of city D=\frac{1}{2}(-16) feet  

B.The elevation of city D=-8 feet

because it is 8 feet below the sea level therefore, it takes  negative.

Step-by-step explanation:

We are given that

The elevation of city A=-80 feet

The elevation of city C=-16

The elevation of city D=1 over 2 of the city C

A.We have to find an expression to represent the elevation in feet of city D.

The elevation of city D=\frac{1}{2}(-16) feet  

B.We have to solve the expression and explain .

The elevation of city D=\frac{1}{2}\times (-16)=-8 feet

The answer is negative because the elevation is below the sea level.

The sea level is like as origin and the elevation measured on the negative y- axis below the origin means sea level.

So, the elevation of city D is 8 feet below the sea level and taken -8.
