Tom draws two cards from a deck. One of them is 7. The sum of the numbers on the two cards is 13. What number is on the other card?
Changing your name still makes 6+7 = 13
To find out the number on the other card, we first need to determine what the number on the first card is. We know that one of the cards is a 7, so we can subtract this number from the sum of the two numbers to find the other card.
The sum of the two numbers is 13, and we know that one of the numbers is 7. Therefore, let's subtract 7 from 13:
13 - 7 = 6
So, the number on the other card is 6.
Let's assign the number on the other card as "x".
Given that one of the cards is a 7, the sum of the two cards is 13. So we can set up an equation:
7 + x = 13
To find the value of x, we can solve this equation:
x = 13 - 7
x = 6
Therefore, the number on the other card is 6.
