Chloe bought 5 sets of books. She donated 9 of her books to her school. She has 26 books left. How many books were in each set? please help

7 books in each set.

Step-by-step explanation:

If you add the nine books that she donated (9) to the number of books that are left over (26) you would have 35. And since their are 5 sets you would divide 35 by 5 and get 7.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
