Melissa is 9 years old. how old will she be in x years?

Taking that you didn't provide any other information about the values of x..

The only plausible answer, which probably isn't your case but still can be valid out of context is 19.

Step-by-step explanation:

"X" is 10 in Roman numbers.

9 + 10 = 19

(But I suppose that you had more details to the question that you didn't yet share :) )

OR.. the answer might be an algebraic expression..

"9+x" years old.

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
