David owns 24% of a partnership. Robert owns 48% of the partnership. If Sam is the third partner, what percent of the partnership does he own?

Sam owns 28% of partnership.

Step-by-step explanation:

Given,

David owns 24% of a partnership.

Robert owns 48% of the partnership.

To find the partnership of Sam.

Let, total partnership is 100

Then, David owns = 24

Robert owns = 48

Total partnership they both own = (24+48) = 72

So,

Sam own = 100 - 72 = 28

Hence,

Sam owns 28% of partnership.

-8, 28

Step-by-step explanation:

║10-x║= 18

we remove the bars and we know that there are two result for this, one positive and one negative.

10-x= 18    

-x= 18-10

x= 8/-1

x= -8

-(10-x)= 18

-10 +x= 18

x=18+10

x=28

final answer is -8, 28
