Math question: If x represents the number of days it takes for a car to travel 82 miles at a constant speed of 3.5 miles per hour, what is the value of x?

To find the value of x, we can use the formula: distance = speed × time. Given that the distance is 82 miles and the speed is 3.5 miles per hour, we can rearrange the formula to solve for time: time = distance / speed. Plugging in the values, we get time = 82 miles / 3.5 miles per hour = 23.43 hours. Therefore, it would take approximately 23.43 hours for the car to travel 82 miles at a constant speed of 3.5 miles per hour.

Math question: The sum of a number and its square is 1806. What is the number?

Let the number be x. According to the given information, we have the equation x + x^2 = 1806. Rearranging, we get x^2 + x - 1806 = 0. By solving this quadratic equation, we find that x = 41 or x = -44. However, since the question states the number is positive, the answer is 41.

Question: If 82 is multiplied by 3, added to 16, subtracted by 7, squared, and then divided by 2, what is the final result?

To find the result, we first multiply 82 by 3, getting 246. Then, we add 16 to this, yielding 262. Subsequently, subtracting 7 gives us 255. Next, we square this value, resulting in 65,025. Lastly, dividing by 2 yields the final answer of 32,512.5.
