20 pts, try to find short story and novel pages, A novel has 13 times as many pages as a short story. The combined number of pages in the books is 448 pages. How many pages are in each book?
Short Story:
Novel:
Answers
Answer:
short story has 32 pgs
novel has 416 pgs
Step-by-step explanation:
a novel (N) has 13 times as many pages as a short story (x) so, N = 13X
total pages is the equation N + x = 448
plug the equation for N into this
13x + x = 448, combine like terms
14x = 448, divide both sides by 14
x = 32. so now we know that the short story has 32 pages. subtract that from 448. and the novel has 416 pages.
There are 32 pages in the short story and 416 pages in the novel.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
Let x be the number of pages in the short story.
We know that the novel has 13 times as many pages as the short story, so the number of pages in the novel is 13x.
The combined number of pages in the books is the sum of the number of pages in the short story and the number of pages in the novel, which is x + 13x = 14x = 448 pages.
So the number of pages in the short story is x = 32 pages.
And the number of pages in the novel is 13x = 13 × 32 = 416 pages.
