Answer:
Step-by-step explanation:
14x - y = -1
14x = y -1
14x +1 = y
Substitute into other problem:
3x + 2(14x +1) =13
3x + (28x + 2) = 13
31x + 2 = 13
31x = 11
x = 11/31
Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
<h3>How to calculate greater mean number of pages?</h3>
From the complete information, we can deduce that the number of each pile of book is given as follows:
<u>For pile W;</u>
Red books = 10 × 5 = 50 red books.
Blue books = 5 × 5 = 25 blue books.
Therefore, total books in pile W = 50 + 25 = 75 books.
Mathematically, the mean for each pile can be calculated by using the following formula:
Mean = [F(x)]/n
Mean = 75/10
Mean = 7.5.
<u>For pile Y;</u>
Red books = 10 × 5 = 50 red books.
Mean = [F(x)]/n
Mean = 50/5
Mean = 10.
In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
