    Number of minutes Denzel still has to practice after x days, N (x) = 210 - 30x

    Step-by-step explanation:

    Denzel must practice piano for 210 minutes each week.

    Total practice needed = 210 minutes

    Total minutes practicing per day = 30 minutes

    Let x be the number of days practiced

    Total minutes practices after n days = 30x

    Total remaining minutes = 210 - 30x

    Number of minutes Denzel still has to practice after x days, N (x) = 210 - 30x
