Set contain all the elements present in both the sets.
<u>Step-by-step explanation:</u>
Definition:
The union of two mathematical sets can be defined as the set that consists of all the elements present in both the sets without the repetition of elements.
Consider, A and B be the sets.
A = {1,7,5,6,0}
B = {2,3,4,5,6}
U is the symbol of union of sets, so A U B = {1,2,3,4,5,6,7,0}
Here 5 and 6 are the elements present in both the sets, so written only once in the set of A U B.
Answer:
Each pair of shoes cost 26$
Step-by-step explanation:
<em>find the total cost for shirts</em>
2 shirts * 12$ each
2 * 12 = 24
they spent 24$ on shirts
<em>create an equation</em>
24$ shirts + x$ shoes = 76$
24 + x = 76
<em>subtract 24 from both sides of the equation</em>
24 + x - 24 = 76 - 24
x = 76 - 24
x = 52
they bought 2 pairs of shoes that cost the same amount
52 = x + x
52 = 2x
<em>divide both sides of the equation</em>
52/2 = 2x/2
52/2 = x
26 = x
each pair of shoes cost 26$
Answer:
35
