Question

Max is thinking of a double fact. The sum is greater than the sum of 6+4 but less than the sum of 8+5 what fact is max thinking of?

Answer 1

Answer: 6 + 6 = 12.

Explanation:

The word double has a typo: it is doubles.

So, the question is: "Max is thinking of a doubles fact. The sum is greater than the sum of 6+4 but less than the sum of 8+5 what fact is Max thinking of?"

In the adequate context (learning the first concepts in algebra), it means that Max is thinking of a fact of doubles. For example, it may  be the doubles that can result of throwing two dices: 1 and 1, 2 and 2, 3 and 3, ...

Hence, you are looking for a number that repeated (added to it self) the sum is greater than the sum of 6+4 but less than the sum of 8+5.

The sum of 6 + 4 = 10.  So, the number must be greater than 10, meaning that 10 is not included, and the number may be 11, 12, 13, ...

The sum of 8 + 5 = 13. So, the number must be less than 13, meaning that 13 is not included, and the number may be ... 10, 11, 12.

Joining the two conditions the number can only be 11 or 12.

Being 11 an odd number it cannnot result of the sum of two equals number, but 12 can: 6 + 6 = 12. And that is fact Max is thinking of.

Answer 2

6=4 is 11 and 8and 5 is 13 that the answer to your question
