Question: If you subtract 75 from a number and then divide the result by 3, the quotient is equal to the original number. What is the number?

Let's assume the number you're looking for is 'x'. We can write this information as an equation: (x - 75) ÷ 3 = x. To solve for 'x', we'll first distribute the division by multiplying both sides by 3, giving us x - 75 = 3x. Next, we isolate 'x' by subtracting 'x' from both sides, which gives us -75 = 2x. To get 'x' alone, we divide both sides by 2, yielding -37.5 = x. Therefore, the number you're looking for is -37.5.

Question: What is the sum of the first ten prime numbers greater than 140 but less than 170?

To find the answer, we need to identify the prime numbers in the given range. Prime numbers between 140 and 170 are 149, 151, 157, 163, and 167. Adding them up gives 787. Therefore, the sum of the first ten prime numbers greater than 140 but less than 170 is 787.

Question: What is the product of 8 multiplied by 13, divided by the square root of 2, and subtracted from 156?

To find the answer, we first calculate 8 multiplied by 13, which equals 104. Then, we find the square root of 2, approximately equal to 1.414. Dividing 104 by 1.414, we get 73.4615 (rounded to 4 decimal places). Finally, subtracting 73.4615 from 156 gives us 82.5385 (rounded to 4 decimal places). Therefore, the answer is approximately 82.5385.
