Answer:
The numbers are 19 and 5
Step-by-step explanation:
Given
Let the numbers be ![x\ and\ y.](https://tex.z-dn.net/?f=x%5C%20and%5C%20y.)
So:
--- First statement
--- second statement
Required
Find x and y
Substitute
in ![x*y = 95](https://tex.z-dn.net/?f=x%2Ay%20%3D%2095)
![(9 + 2y) * y = 95](https://tex.z-dn.net/?f=%289%20%2B%202y%29%20%2A%20y%20%3D%2095)
![9y + 2y^2 = 95](https://tex.z-dn.net/?f=9y%20%2B%202y%5E2%20%3D%2095)
Rewrite as:
Expand
![2y^2 -10y +19y- 95 = 0](https://tex.z-dn.net/?f=2y%5E2%20-10y%20%2B19y-%2095%20%3D%200)
Factorize
![2y(y -5) +19(y- 5) = 0](https://tex.z-dn.net/?f=2y%28y%20-5%29%20%2B19%28y-%205%29%20%3D%200)
![(2y +19)(y- 5) = 0](https://tex.z-dn.net/?f=%282y%20%20%2B19%29%28y-%205%29%20%3D%200)
Solve for y
or ![y - 5 = 0](https://tex.z-dn.net/?f=y%20-%205%20%3D%200)
or ![y = 5](https://tex.z-dn.net/?f=y%20%3D%205)
or ![y=5](https://tex.z-dn.net/?f=y%3D5)
Since the numbers are positive, we take only:
![y=5](https://tex.z-dn.net/?f=y%3D5)
Substitute
in ![x = 9 + 2y](https://tex.z-dn.net/?f=x%20%3D%209%20%2B%202y)
![x = 9 + 2 * 5](https://tex.z-dn.net/?f=x%20%3D%209%20%2B%202%20%2A%205)
![x = 9 + 10](https://tex.z-dn.net/?f=x%20%3D%209%20%2B%2010)
![x = 19](https://tex.z-dn.net/?f=x%20%3D%2019)
<em>The numbers are 19 and 5</em>
Step-by-step explanation:
When studying sets of numbers students have certain misconception
1) the correct of writing the tabular notation form
2) the differentiation between sets ( example certain sets have zero and certain do not have a zero - example 2 all integers are rational numbers but all rational numbers are not integers)
3) types (kinds ) of sets . ( onto - into and binary relation)
4) Domain and Range of sets

to evenly split it and Lilly still gets some divide by 9
every one gets 5,069 dollars
or she could ignore those greedy peeps and just share with her dad and get 22,792.50 dollars
