Math question: If a number is doubled, then tripled, and 50 is added, the result is 3919. What is the number?

Let's denote the unknown number as x. From the given information, we can set up the equation (2 * 3 * x) + 50 = 3919. Simplifying, we have 6x + 50 = 3919. Subtracting 50 from both sides, we get 6x = 3869. Finally, dividing both sides by 6 gives the solution x = 644. Hence, the number is 644.

Math question: What is the sum of the digits in the number 3919?

To find the sum of the digits in 3919, we add the individual digits 3, 9, 1, and 9 together. Adding them, we get: 3 + 9 + 1 + 9 = 22. Therefore, the sum of the digits in 3919 is 22.

Math question: What is the sum of the digits when 3919 is divided by 3 and then multiplied by 5, subtracting the product from 100?

To find the sum of the digits when 3919 is divided by 3, we add its digits together: 3 + 9 + 1 + 9 = 22. Then when we multiply 22 by 5, we get 110. Subtracting the product from 100, we have 100 - 110 = -10. Therefore, the answer is -10.
