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?

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
