Math question: If you add 250 to a number and then subtract 20% of that number, the result is 7550. What is the original number?

Let's assume the unknown number as x. According to the given information, we can write the equation: x + 250 - 0.2x = 7550 Simplifying the equation: 0.8x + 250 = 7550 0.8x = 7550 - 250 0.8x = 7300 x ≈ 9125 Therefore, the original number is approximately 9125.

Math question: If 7550 is expressed as a sum of two numbers, where one number is five times the other number, what are the two numbers?

Let's assume the smaller number is x. Since the larger number is five times the smaller number, it can be represented as 5x. Therefore, we have the equation x + 5x = 7550. Combining like terms, we get 6x = 7550. Dividing both sides by 6, we find x = 1258.33 (rounded to two decimal places). Hence, the larger number is 5 * 1258.33 = 6291.67 (rounded to two decimal places). Therefore, the two numbers that sum up to 7550 are approximately 1258.33 and 6291.67.

What is the largest prime factor of 7550?

To find the largest prime factor of 7550, we first need to prime factorize the number. The prime factorization of 7550 is 2 * 5^2 * 151. Now, we look for the largest prime number in this factorization, which is 151. Therefore, the largest prime factor of 7550 is 151.
