Math Question: If you divide a number by 10, multiply it by 5, subtract 28, and finally add 18, you get the number 1690. What is the original number?

Let's solve this math problem step by step. Let the original number be x. According to the given conditions, we have (x / 10) * 5 - 28 + 18 = 1690. Simplifying further, we get 5x/10 - 10 = 1672. Multiplying both sides by 10 gives 5x - 100 = 16720. Adding 100 to both sides yields 5x = 16820. Finally, dividing both sides by 5 gives x = 3364. Therefore, the original number is 3364.

What is the square root of 1690, rounded to the nearest whole number?

The square root of 1690 is approximately 41.

Question: Divide a number by 13 and then add 102. Take the result and multiply it by 7. Finally, subtract 10 from the product to get 1690. What is the original number?

Let's assume the original number is x. We can set up the equation: ((x / 13) + 102) * 7 - 10 = 1690. Solving this equation, we perform the reverse order of operations. First, we add 10 to 1690 to get 1700. Next, we divide it by 7 to obtain 242.857. Subtracting 102 from this gives us 140.857. Finally, multiplying by 13 gives the original number x as approximately 1831.
