Answer:
Can I please have more details on what your question is?
Step-by-step explanation:
10
The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.
That literally means the numbers '5' and '12' written like this: 5 + 12
represent the sum of 5 and 12, which is the same as 5 + 12 (because the sum is when all the numbers are added up).
So it's saying 5 + 12 equals to 17.
Do you get it?
