Lasy year, Kristen read a total of 30 fiction and non-fiction books. The number of non-fiction books was 5 less than 4 times the
number of fiction books. What are the total number of fiction and non-fiction books that Kristin read?
1 answer:
Answer:
- 7 fiction books
- 23 non-fiction books
Step-by-step explanation:
The number of non-fiction read was 5 less than 4 times the number of fiction books.
Assume fiction books are x.
An equation representing this would be:
x + (4x - 5) = 30
5x - 5 = 30
5x = 30 + 5
x = 35 / 5
x = 7 fiction books
Non-fiction books:
= 4x - 5
= 4 * 7 - 5
= 23 non - fiction books

Sn= 11/2(34)
Sn = 11x17
=187.
