Question

Katie spent m minutes practicing her trumpet on

Answer 1

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.
