Math Question: If I add 5 to a number, multiply it by 8, and then subtract 18, finding the square root of the result yields 212. What is the number?

Let's assume the number we are looking for is x. According to the given information, (√((8(x + 5) - 18)) = 212. Simplifying this equation, we have (√((8x + 40) - 18)) = 212. By squaring both sides, we get 8x + 40 - 18 = 44944. Solving this, we find 8x + 22 = 44944, leading to 8x = 44922. Finally, dividing both sides by 8, we obtain x = 5615.5. The number is 5615.5.

Question: If the number 212 is divided by 4 and then multiplied by 5, what is the result?

To solve this, we start by dividing 212 by 4, which gives us 53. Then, we multiply 53 by 5, resulting in 265. Hence, the answer is 265.

Math Question: Consider the number 212. If we multiply it by 7, subtract 316, divide the result by 2, and then add 9 to it, what is the final value?

To find the final value, let's follow the given steps. Step 1: Multiply 212 by 7 to get 1,484. Step 2: Subtract 316 from 1,484, resulting in 1,168. Step 3: Divide 1,168 by 2, which equals 584. Step 4: Finally, add 9 to 584 to get 593. Therefore, after multiplying by 7, subtracting 316, dividing by 2, and adding 9, the final value for the number 212 is 593.
