There are five times as many students as teachers at CHS9. There is a total of 570 students and teachers combined at CHS9. How many students are there?
Let's assume the number of teachers is T.
The number of students is 5*T.
The total number of students and teachers is T + 5*T = 570.
Combining like terms, we get 6*T = 570.
Dividing both sides by 6, we get T = 570/6 = <<570/6=95>>95.
The number of students is 5 * 95 = <<5*95=475>>475. Answer: \boxed{475}.
