Math question: If I subtract 28.5 from a number and divide the result by 6, I get 9. What is the number?

Let's call the number 'x'. The math question states that (x - 28.5) divided by 6 equals 9. To solve for 'x', we can multiply both sides of the equation by 6 to get x - 28.5 = 54. Adding 28.5 to both sides of the equation, we find x = 82. Therefore, the answer is 82.

Math question: What is the sum of all multiples of 8 between 164 and 500 inclusive?

To find the sum of multiples of 8 between 164 and 500, we need to determine how many multiples there are and then calculate their sum. Taking the highest multiple of 8 less than or equal to 500, which is 496, subtracting the highest multiple less than 164, which is 160, we get 496 - 160 = 336. Since each multiple is 8 apart, we can find the number of terms by dividing the difference by 8, which gives 336 / 8 = 42. Now, 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. Plugging in the values, S = (42/2)(160 + 496) = 21 × 656 = 13,776. Therefore, the sum of all multiples of 8 between 164 and 500 is 13,776.

Math question: If 164 apples are divided equally among a group of students, how many apples will each student receive?

To find the number of apples each student receives, we divide the total number of apples (164) by the number of students. Let's assume there are x students. Therefore, each student will receive 164/x apples. Expanded answer: To solve this problem, let's say there are 10 students in total. Dividing 164 by 10 would give each student 16 apples. However, what if there were only 5 students? Dividing 164 by 5 would give each student 32.8 apples, which is not possible since we can't have a fraction of an apple. So, the number of students must be a factor of 164. The factors of 164 are 1, 2, 4, 41, 82, and 164. Hence, if there is only one student, they will receive 164 apples. If there are two students, each will receive 82 apples. For four students, each will receive 41 apples. However, if there are no constraints on the number of students, we can only say that each student will receive 164/x apples. The exact number of apples each student receives would depend on the total number of students in this case.
