Math question: If a number is increased by 85 and then divided by 3, the result is 92. What is the original number?

Let's assume the original number is x. We can set up the equation as (x + 85) / 3 = 92. To solve for x, first multiply both sides of the equation by 3 to get x + 85 = 276. Next, subtract 85 from both sides to isolate x, giving us x = 191. Therefore, the original number is 191.

Math question: What is the sum of all the two-digit odd numbers greater than 200 and smaller than 300?

To find the sum of the two-digit odd numbers greater than 200 and smaller than 300, we first need to identify these numbers. Starting from 201, we see that the numbers follow a pattern of increasing by 2 each time. So, the sequence of two-digit odd numbers between 200 and 300 is: 201, 203, 205, ..., 297. To find the sum, we can use the formula for the sum of an arithmetic series: S = (n/2)(a + l) Where S is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, there are (297 - 201)/2 + 1 = 48 terms. The first term, a, is 201, and the last term, l, is 297. Using the formula, we get: S = (48/2)(201 + 297) = 24(498) = 11,952 Therefore, the sum of all the two-digit odd numbers greater than 200 and smaller than 300 is 11,952.

Math Question: What is the sum of the digits of the number 277?

To find the sum of the digits, we add the individual digits together. For the number 277, the sum of the digits would be 2 + 7 + 7 = 16. Explanation: Since 277 has three digits, we need to add each digit separately. The digit 2 represents 200, the digit 7 represents 70, and the final 7 represents 7. Summing the values, we get 200 + 70 + 7 = 277.
