Last week tiffany practiced her bassoon a total of 7 hours. this was 2 hours more than she practiced the previous week. how many hours did tiffany practice the previous weeks?

If Tiffany practiced 2 hours more than she did last week, this means she practiced 2 hours less than the next week.

7 - 2 = 5

Tiffany practiced 7 hours one week and 5 hours the previous week.

7 + 5 = 12

Tiffany practiced 12 hours total in the 2 previous weeks.

Hope this helps!

Idon’t know i’m sorry
