Last week Betty practiced her guitar for 45 minutes on Monday, 25 minutes on Tuesday, 35 minutes on Wednesday, 20 minutes on Thursday, and 40 minutes on Friday. What was the mean number of minutes that she spent practicing each day?

33 minutes

Step-by-step explanation:

To find the mean, you first must add up the values given.

45 + 25 + 35 + 20 + 40 = 165

165/5 = 33

The mean number of minutes she spent practicing is 33.

5x+10 is the correct one
