Question

A high school teacher teaches three classes per day. Her first class has double the number of students as her second class, while her third class has 13 more students than her second class. In total, she teaches 53 students. The equation 2x + x + (x +13) = 53 represents this scenario, where x is the number of students

in her second class.
How many students are in her second class?

Answer 1

Answer: 10

Step-by-step explanation: first subtract 13 from 53 which gives you 40 then divide 40 by 4 which gives you 10 but because your first class is double more than your second class it has 20 students and your second class has 10 students and because you have to add that 13 back in your third class has 23 students
