Question
Solution 1
Sure, let's solve this step by step:

Let's denote the number of cards labeled with a 4 as x and the number of cards labeled with a 5 as y. We know that x + y = 18 because there are 18 cards in total.
-
We also know that the sum of all the numbers on the cards is divisible by 17. This gives us Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
