Ella is stuffing envelopes. she has 48 red pages, 25 white pages, and 84 blue pages. if she need to put 2 red pages, 1 white pages, and 4 blue pages in every envelope to make it complete, how many complete envelopes can she make?

Divide each number of pages she has, with the number of pages required.

48 red pages divided by 2 red pages.

48 ÷ 2 = 24

25 white pages divided by 1 white pages.

25 ÷ 1 = 25

84 blue pages divided by 4 blue pages.

84 ÷ 4 = 21

Now add the total amount.

24 + 25 + 21 = 70

Ella can make 70 envelopes.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
