If morgan and kira have a number of jelly beans in a ratio of 5 : 3. kira and mann have a number of jelly beans in a ratio of 6 : 1 how many does mann have? explain and show your work

Step-by-step explanation:

Kira has 3/8 of the total of Jelly Beans available. Morgan has the other 5/8

So if there are 56 Jelly beans in total 3/8 * 56 = 21 which would be Kira's share.

Morgan would have 5/8 * 58 = 35 Jelly beans (Not that this is really relevant).

Now Kira and Mann have a ratio of 6:1 which means that she has 6/7 of the total between those two. He therefore must have 1/7 of the total.

Her total is 21.

1/7 of 21 = 3

Therefore Mann would have 3 jelly beans.

3/8 * 1/7 is the total the number of Jelly Beans that he would have if the total was N

N(3/8 * 1/7) = N (3/56)

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
