Genrish500 [490]

Answer:

9/4

Step-by-step explanation:

1 2/7=9/7

2 1/3=7/3

--------------

9/7+7/3x+3/14+x=9

18/14+3/14+7/3x+3/3x=9

21/14+10/3x=9

10/3x=9-21/14

10/3x=9-3/2

10/3x=18/2-3/2

10/3x=15/2

x=(15/2)/(10/3)

x=(15/2)(3/10)

x=45/20

simplify

x=9/4

11) If A = {19, 20, 21, 24} and B = {17, 19, 20, 22), list the elements of A U B.

Elodia [21]

Answer:

A U B = {17, 19, 20, 21, 22, 24}

Step-by-step explanation:

The symbol U is the union symbol, which denotes the union of two sets.

This means that given two sets A and B, the expression

A U B

indicates all the elements that belong to either set A or set B.

In this problem, we have the following two sets:

A = {19, 20, 21, 24}

B = {17, 19, 20, 22}

We can therefore list all the elements belonging to either set A or set B, they are:

17, 19, 20, 21, 22, 24

So, the expression A U B indicates the set:

A U B = {17, 19, 20, 21, 22, 24}
