Respuesta :

Answer:

  • 7m minutes

Step-by-step explanation:

We know that:

  • 3 days of practice = Monday + Tuesday + Wednesday
  • Monday = m
  • Tuesday = m + 6
  • Wednesday = 5m - 6

Solution:

  • 3 days of practice = Monday + Tuesday + Wednesday
  • => 3 days of practice = m + m + 6 + 5m - 6

[Simplifying]

  • => 3 days of practice = 7m - 6 + 6

[Final Answer]

  • => 3 days of practice = 7m

Hence, the total number of minutes she practiced over the course of the three days is 7m minutes.
