Weegy: The sum of three certain consecutive numbers is 240. x + x +2 + x + 4 = 240, 3x + 6 = 240, 3x = 240 -6 ; 3x = 234 , x = 234/3 = 78, x = 78 , x + 2 = 78 + 2 = 80 , x + 4 = 78 + 4 = 82.

Amy, Doug, and Ginger took a math test. Amy scored 12 points higher than Doug, and Ginger scored twice as many points as Doug. The total points the three friends received was 208. Doug scored 49 points on the test.
Solution: Amy(A): D + 12
Doug(D):D
Ginger(G):2D
SumOfAll(S)=208 : Total points / sum of all three friends
(D+12)+D+2D=208
D+12+3D=208 - transpose 12 to the right side
4D=208-12
4D = 196 - divide both sides by 4
D=49
Therefore, Doug scored 49
