Math question: If a number is decreased by 20 and then multiplied by 8, the result is 320. What is the original number?

Let's assume the original number is 'x'. According to the given data, (x - 20) multiplied by 8 equals 320. Therefore, we can write the equation 8(x - 20) = 320. By distributing 8, we get 8x - 160 = 320. Solving for x by adding 160 to both sides gives us 8x = 480. Finally, dividing both sides by 8, the original number 'x' equals 60. Hence, the original number was 60.

Question: If you start with the number 320 and subtract 8 three times, multiply the result by 5, divide by 2, add 10, and then multiply by 3, what is the final result?

Starting with the number 320, subtracting 8 three times gives us 320 - (8 * 3) = 320 - 24 = 296. Multiplying 296 by 5 gives us 296 * 5 = 1480. Dividing 1480 by 2 gives us 1480 / 2 = 740. Adding 10 gives us 740 + 10 = 750. Finally, multiplying 750 by 3 gives us 750 * 3 = 2250. Therefore, the final result is 2250.

Math question: What is the sum of the prime factors of 320?

To find the prime factors of 320, we divide it by prime numbers until it cannot be divided further. The prime factors of 320 are 2, 2, 2, 2, and 5. Adding these prime factors (2 + 2 + 2 + 2 + 5) gives us the sum of 13. Therefore, the sum of the prime factors of 320 is 13.
