Answer:
The cost of 10 ice-cream cones is <u>40 dollars</u>.
Step-by-step explanation:
Here we have given that the cost of 5 ice-creams cone is 20 dollars. So, finding the cost of 1 ice-cream cone.
Hence, the cost of 1 ice-cream cone is 4 dollars.
Now, we know the cost of 1 ice-cream cone. Thus, finding the cost of 10 ice-cream cones.
Hence, the cost of 10 ice-cream cones is 40 dollars.
Answer:
(5, - 6)
Step-by-step explanation:
Given the 2 equations
6x + 3y = 12 → (1)
6x - 5y = 60 → (2)
Multiply (2) by - 1 and add to (1) will eliminate the term in x
- 6x + 5y = - 60 → (3 )
Add (1) and (3) term by term
(6x - 6x) + (3y + 5y) = (12 - 60)
8y = - 48 ( divide both sides by 8 )
y = - 6
Substitute y = - 6 into (1) or (2) and siolve for x
Using (1), then
6x - 18 = 12 ( add 18 to both sides )
6x = 30 ( divide both sides by 6 )
x = 5
Solution is (5, - 6)
The Two sets, A and B, are said to be disjoint sets if A n B=ϕ
<h3>What does it mean for two sets to be disjoint?</h3>
- Disjoint sets are a pair of sets that do not share any elements. For instance, sets A=2,3 and B=4,5 are not connected sets.
- When two sets don't share elements, they are considered disjoint sets. In other words, the null set will result if we find the intersection of two sets. The process is straightforward; two sets are given in this procedure.
- When using a disjoint set union, it is possible to add new sets, combine existing sets, and check whether two sets of elements are the same in almost real-time.
