Where are your questions?
Answer: 825 minutes
Step-by-step explanation: We know there is a total of 15 people in the book club. We also know that 10 people each read an average of 65 minutes each day, and the remaining 5 people read for an average of 35 minutes each day.
To find the total amount f minutes read, simply multiply the amount of people by the minutes read.
10 x 65 = 650 total minutes read if 10 people each read 65 minutes for one day.
5 x 35 = 175 total minutes read if 5 people each read for 35 minutes in one day.
Now, simply add the total minutes read to find the reading time fr the entire book club each day.
650 + 175 = 825 average reading time for the entire book club each day.
The answer would be 10.5 <span />
Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
