Johan practices the drums for 45 minutes on Saturdays and 25 minutes on most weekdays. Last week he practiced 120 minutes. How many weekdays did he practice? write an equation of px + 1 = r to represent this problem. ___x+___=___
120
25
45
Let's assume that Johan practiced on x number of weekdays. Since he practiced for 25 minutes on most weekdays, we can multiply 25 by x to get the total minutes he practiced on weekdays.
On Saturdays, Johan practiced for 45 minutes, so we add 45 to the total minutes he practiced on weekdays.
Therefore, the equation to represent the problem is:
25x + 45 = 120
