Can somebody me with this? not good at math

{ 2, 3, 5, 8}

Step-by-step explanation:

A = { 2, 3, 5, 8}

B = { 3, 5, 7}

C = { 2, 4, 8}

BUC = { 2, 3, 4, 5, 7, 8}

An(BUC) = { 2, 3, 5, 8}

Union of a set

The union of two sets is a new set that

contains all of the elements that are in

at least one of the two sets. The union

is written as A U B

Intersection

The intersection of two sets is a new

set that contains all of the elements

that are in both sets. The intersection is

written as A n B or "A and B"

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
