Final answer:
The expression to find the total number of minutes spent on homework and watching TV in 5 days is 5(m + 30), which equals 5m + 150 minutes. This is calculated by adding the daily time of both activities and then multiplying by the number of days.
Step-by-step explanation:
To find the total number of minutes spent on both activities in 5 days, you need to calculate the daily total and then multiply it by 5. First, we add the time spent on homework (m minutes) to the time spent watching TV (30 minutes) for a single day. This gives us m + 30 minutes per day. Then, to find the total time for 5 days, we multiply the daily total by 5:
5 (m + 30) = 5m + 150 minutes.
This expression represents the total number of minutes you do both activities over the course of 5 days. The reasoning behind this is that each day, you spend a total of m + 30 minutes on both activities, and over 5 days, this time accumulates linearly.
