Lindsay practices the guitar 50 minutes on Saturday and 30 minutes on most weekdays. Last week she practiced 140 minutes. How many weekdays did she practice? Write an equation in the form px+q=r to represent this problem.(2 points)?
Let x be the number of weekdays Lindsay practiced the guitar.
Since she practiced 30 minutes on most weekdays, the total time spent on weekdays is 30x.
Since she practiced 50 minutes on Saturday, the total time spent on Saturday is 50.
The total time Lindsay practiced last week is the sum of the time spent on weekdays and Saturday, which equals 140 minutes.
Therefore, the equation in the form px+q=r is: 30x + 50 = 140.
