Question: If you subtract a number from 530 and then divide the result by 2, what is the number that you started with?

To find the number, let's call it x, we can set up the equation as (530 - x) ÷ 2 = x. First, multiply both sides of the equation by 2 to eliminate the denominator: 530 - x = 2x. Next, add x to both sides to isolate terms with x: 530 = 2x + x. Combine like terms: 530 = 3x. Now, divide both sides of the equation by 3 to solve for x: x = 530 ÷ 3 = 176.67 (rounded to two decimal places). Therefore, the number we started with is approximately 176.67.

Math question: What is the value of 530 divided by 2, multiplied by 7, minus 100?

To find the answer, we start by dividing 530 by 2, which equals 265. Then, we multiply this result by 7, giving us 1855. Lastly, subtracting 100 from 1855 yields a final answer of 1755. Therefore, 530 divided by 2, multiplied by 7, and subtracting 100 equals 1755.

Math question: What is the sum of 530 and the product of its digits?

To find the sum of 530 and the product of its digits, we first calculate the product of the digits: 5 * 3 * 0 = 0. Next, we add this product to 530: 530 + 0 = 530. Therefore, the answer is 530.
