Ralph is 3 times as old as sara. in 6 years, ralph will be only twice as old as sara will be then. find ralph's age now.

which of the following equations could be used to solve the problem?

3x + 2x
x + 6 = 2(3x + 6)
3x + 6 = 2(x + 6)
3x + 6 = 2x + 6

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.
