Eva goes to soccer practice for about 45 minutes most weekdays. And games are 60 minutes on Saturday. Last week she practiced 180 minutes. How many weekdays did she practice? Write an equation in the form px+q=r to represent this problem.
Let x represent the number of weekdays Eva practiced.
The total time she practiced on weekdays is 45x.
The total time she practiced on Saturday is 60 minutes.
The total time she practiced is 45x + 60.
We know the total time she practiced last week was 180 minutes.
So the equation is 45x + 60 = 180. Answer: \boxed{3}.
