Answer:
(15/2, -5/2)
Step-by-step explanation:
1. Sub x=5y+20 into 2x+2y=10 and simplify as shown below.
2(5y+20)+2y=10
10y+40+2y=10
12y+40=10
12y=-30
y=-30/12
y=-5/2
2. Sub in y=-5/2 into 2x+2y=10 to find x and simplify as shown below.
2x+2(-5/2)=10
2x-5=10
2x=15
x=15/2
12 bottles = 6 liters
--------------------------------------------------------
Find 1 bottle
--------------------------------------------------------
12 bottles = 6 liters
1 bottle = 6 ÷ 12
1 bottle = 0.5 liters
1 bottle = 500 ml
--------------------------------------------------------
Answer: 1 bottle = 500 ml

Using the combination formula, it is found that there are
ways to deal the cards to the six players.
The order in which the cards are handed to each player is not important, hence the <em>combination formula</em> is used to solve this question.
<h3>What is the combination formula?</h3>
is the number of different combinations of x objects from a set of n elements, given by:

In this problem:
- For the first player, 5 cards are taken from a set of 48.
- For the second player, they are taken from a set of 43.
- For the third for a set of 38, for the fourth from a set of 33, for the fifth from a set of 28 and for the sixth from a set of 23, hence:


There are
ways to deal the cards to the six players.
