Best ResponseYou've already chosen the best response.1I think it depends on the definition of prime numbers your teacher chose. I choose the definition that they are natural numbers greater than 1 and are only divisible by 1 and itself. For example: 13 since 13 and 1 are it's only factors

Best ResponseYou've already chosen the best response.1So do you think you can now list the prime numbers between 1 and 10 (not including 10 since it doesn't say equal to)?

Best ResponseYou've already chosen the best response.1A math teacher is preparing an exam each of his Algebra class. Mathalino and Mathmatalino, covering topics A (circles) and B (inequalities). He wants to design the exams so that both classes will have the same number of questions on A and also on B. Each question on A is worth 15 points in section Mathalino and 20 points in section Mathmatalino while each question on B is worth 10 points in section Mathalino and 5 points in section Mathmatalino. If the total number of points in both exams is 100, how many questions should he ask on each topic?
