Question

Linda's practices the guitar 50 minutes on Saturday and 30 minutes on most weekends last week she practiced 140 minutes how many weeks days did she practice write an equation in the form of PX + q = r to represent this problem

Answer 1

Let x represent the number of weekdays Linda practiced.
Since there are 5 weekdays in a week, she practiced for 30 minutes x times during the weekdays: 30x.
Since she practiced for 50 minutes on Saturday, we don't need to include it in the equation.
Therefore, the total number of minutes Linda practiced is 30x + 50, which should equal 140.

The equation in the form of PX + q = r representing this problem is:
30x + 50 = 140
