Final answer:
After Max gives 5 marbles to Tom, he has 2x - 5 marbles left, making option (D) the correct answer.
Step-by-step explanation:
The question is about solving a basic algebra problem involving marbles. John has x marbles and Max has twice as many. This can be written algebraically as Max having 2x marbles.
If Max gives Tom 5 of his marbles, we subtract 5 from the number of marbles Max has, getting 2x - 5.
Therefore, after giving Tom 5 marbles, Max will have 2x - 5 marbles left. Hence, the correct answer is (D) 2x - 5.
