The elevation of city a is 60 feet above sea level; the elevation of city c is 12 feet above sea level. the elevation of city d is 1 over 2 of the elevation of city c. part a: write an expression to represent the elevation, in feet, of city d. (5 points) part b: solve the expression and explain why the answer is negative or positive. (5 points)

Part A:

Part B: 6 feet above sea level and positive

Step-by-step explanation:

The elevation of city A is 60 feet above sea level.

The elevation of city C is 12 feet above sea level.

The elevation of city D is of the elevation of city C.

Part A: Expression which shows Elevation of city D in feet above sea level.

Part B: Simplify the expression of part A

The elevation of city D is 6 feet above sea level.

It would be positive because above sea level height is positive and below sea level takes negative.

were is the equation

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
