Answer: the system of equations that represents this situation are 
12x + 6y = 180
x = 2y
Step-by-step explanation:
Let x represent the number of hardcover books that were sold in a day.
Let y represent the number of paperback books that were sold in a day.
The discount bookstore sells hardcover books for $12 and paperback books for $6. The total sales that day were $180. It means that 
12x + 6y = 180
The number of hardcover books sold that day was twice the number of paperback books. It means that 
x = 2y
 
        
             
        
        
        
Answer:
The correct answer is 0.05882.
Step-by-step explanation:
A deck of cards have 52 cards, 13 cards of each suit.
We are drawing two cards without replacement.
We need to find the probability of getting a diamond as the first card.
Favorable outcomes are 13 and total number of outcomes are 52.
Thus this probability is  .
.
Now for the next draw we again want to pick a diamond card.
Favorable outcomes are 12 and total number of leftover cards are 51.
Thus this probability is  .
.
Now the probability that both cards are diamonds is  ×
 ×  =
 =  = 0.0588235 ≈ 0.05882
 = 0.0588235 ≈ 0.05882

Answer:
6 players
Step-by-step explanation
Since the team has to pay $50 to reserve a table, you need to subtract this fixed cost from $104. Then you divide the total variable cost, $54, by what each player has to pay, $9, to find how many players sit at the team table.
