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

Best ResponseYou've already chosen the best response.1So y = years old of Ralph x = of years old of Sara given: y = 3x using the third function, or C 3x +6 = 2(x +6) 3x = 2x +6 x = 6 Plug in y = 3 (6) y = 18 6 years later: x = 6 +6 = 12 y = 18 + 6 = 24 x+6 = 2x = y+6 So the answer is C
