The elevation of city A is 60 ft above sea level; the elevation of city C is 12 ft above sea level. The elevation of city D is 1/2 of the elevation of city C.
Part A: Write an expression to represent the elevation in ft of city D.
Part B: Solve the expression and explain why the answer is negative or positive.
Part A: 12•1/2= Elevation of city D Part B: The expression would equal 6, 12•1/2=6ft. This is positive because, the number used,12 ft, can be split into and still be positive. If the number was 1, the number would be negative.
