Given:
The sets are 
and 
.
To find:
Whether A and B are disjoint sets or not.
Solution:
Two sets are called disjoint sets if there are no common elements between them.
We have,
Clearly, there is not common elements between the set A and set B.
Therefore, the sets A and B are disjoint sets.

store price = 14 + 0.5(14)
store price = 21
customer price = 21 + 0.08(21)
customer price = 21 + 1.68
customer price = $22.68
24.
formula: A = P(1 + rt)
A = 140(1 + (0.03)(2))
A = 140(1.06)
A = 148.40
interest = 148.40 = 140
interest = $8.40
Hope this helps!! :)
Answer:
The answer is x = 5
Step-by-step explanation:
I added similar elements, then I subtracted 7 from both sides, next I divided by 5 both sides, and lastly I got x = 5 as my answer.

So first, you want to open the parenthesis here.
So, to do that, first look at the symbol before the parenthesis.
In this case it's a -.
So when it's a -, reverse the symbol inside the parenthesis. (This is because if you don't you're subtracting 2x and then adding 8, when really you're subtracting both 2x and 8.)
So,
9x - 2x - 8
Or simplified,
7x - 8
