The length of a rectangle is twice its width, while the perimeter of the rectangle is 36 units. Which system of equations can be used to find the length "L" and the width "W" of the rectangle?
-
2L = W 2L + 2W = 36
-
L = 2W 2L + 2W = 36
-
2L = W L + W = 18
-
L = 2W + 2 36 - W = L

The sum of two factors of 48 is nineteen. The larger factor, x, is one more than five times the smaller factor, y. Which system of equations can be used to find the numbers?
-
X = 19 - y x = 5y + 1
-
X = 19 + y y = 5x + 1
-
X = y + 19 y = 5x - 1
-
X = y - 19 x = 5y + 1
Correct Answer
A. X = 19 - y x = 5y + 1Explanation
The question states that the sum of two factors of 48 is nineteen. This can be represented by the equation x + y = 19. It also states that the larger factor, x, is one more than five times the smaller factor, y. This can be represented by the equation x = 5y + 1. Therefore, the system of equations that can be used to find the numbers is x = 19 - y and x = 5y + 1.Rate this question:

The drama department sold 300 tickets for their last show. Adult tickets cost $10 and student tickets cost $5. If they sold $2750 worth of tickets, what is a reasonable conclusion that can be made about the number of tickets sold?
-
Only adults bought tickets
-
More adults than students bought tickets
-
More students than adults bought tickets
-
The same number of adults and students bought tickets
Correct Answer
A. More adults than students bought ticketsExplanation
Based on the information given, we can conclude that more adults than students bought tickets. This is because adult tickets cost $10, which is more expensive than student tickets that cost $5. Therefore, in order for the drama department to have sold $2750 worth of tickets, they would need to sell more adult tickets than student tickets.Rate this question:

Dustin wants to buy 9 tickets to the circus. The lower balcony tickets cost $20.95 while the upper balcony tickets cost only $12.50. How many of each type of ticket did Dustin buy if he spent $146.30?
-
2 lower balcony tickets, 7 upper balcony tickets
-
4 lower balcony tickets, 5 upper balcony tickets
-
5 lower balcony tickets, 4 upper balcony tickets
-
6 lower balcony tickets, 3 upper balcony tickets
Correct Answer
A. 4 lower balcony tickets, 5 upper balcony ticketsExplanation
Dustin spent a total of $146.30 on 9 tickets. Let's assume he bought x lower balcony tickets and y upper balcony tickets. The cost of x lower balcony tickets would be 20.95x, and the cost of y upper balcony tickets would be 12.50y. Since he bought a total of 9 tickets, we can write the equation x + y = 9. Also, the total cost of the tickets is $146.30, so we can write the equation 20.95x + 12.50y = 146.30. Solving these two equations simultaneously, we find that x = 4 and y = 5. Therefore, Dustin bought 4 lower balcony tickets and 5 upper balcony tickets.Rate this question:

At September Fest, the first dance of the year, the Student Council charged $3 for couples and $2 for singles. If 365 tickets were sold, and the total receipts were $925, which pair of equations would determine the number of each ticket sold?
-
X - y = 365 3x + 2y = 925
-
X - y = 365 x + y = 925
-
X + y = 365 3x + 2y = 925
-
X + y = 925 2x + 3y = 365
Correct Answer
A. X + y = 365 3x + 2y = 925Explanation
The given problem states that there were 365 tickets sold in total and the total receipts were $925. Since the cost of a couple ticket is $3 and the cost of a single ticket is $2, we can set up a system of equations to represent the situation. Let x represent the number of couple tickets sold and y represent the number of single tickets sold. The first equation x - y = 365 represents the total number of tickets sold. The second equation 3x + 2y = 925 represents the total amount of money collected from the ticket sales. Therefore, the pair of equations x + y = 365 and 3x + 2y = 925 would determine the number of each ticket sold.Rate this question:

(3,5)
-
(-1,1)
-
(5,11)
Correct Answer
A. (5,11)Explanation
The solution to the system of equations represented by these tables is (5,11) because when we substitute the x and y values into the equations, they satisfy all the equations.Rate this question:

Dominica has a total of 22 coins in her pocket, all of them nickels and dimes. If the value of the coins is $1.50, then how many nickels does Dominica have?
-
8 nickels
-
10 nickels
-
12 nickels
-
14 nickels
Correct Answer
A. 14 nickelsExplanation
Dominica has a total of 22 coins in her pocket, all of them nickels and dimes. If the value of the coins is $1.50, we can set up the following equation: 0.05n + 0.10d = 1.50, where n represents the number of nickels and d represents the number of dimes. Since we know that the total number of coins is 22, we can also set up the equation n + d = 22. By solving these two equations simultaneously, we find that the number of nickels (n) is 14.Rate this question:

The graph of p = 500 and the graph of p = 25s - 100 intersect at the point (24, 500). If "p" represents the profit and "s" represents sales, what does the intersection best represent?
-
The profit is always 500.
-
The sales are always 24.
-
When the sales are 500, the profit will be 24.
-
When the sales are 24, the profit will be 500.
Correct Answer
A. When the sales are 24, the profit will be 500.Explanation
The intersection of the graphs represents the point where the profit (p) is equal to 500 and the sales (s) is equal to 24. This means that when the sales are 24, the profit will be 500.Rate this question:

Bagels cost $6.99 per dozen and muffins cost $7.50 per dozen. If Rita has at most $75 to spend, which combination of bagels and muffins is not a reasonable purchase?
-
5 dozen bagels and 3 dozen muffins
-
2 dozen bagels and 8 dozen muffins
-
7 dozen bagels and 5 dozen muffins
-
4 dozen bagels and 4 dozen muffins
Correct Answer
A. 7 dozen bagels and 5 dozen muffinsExplanation
The combination of 7 dozen bagels and 5 dozen muffins is not a reasonable purchase because it would cost more than $75. To calculate the cost, we multiply the price per dozen by the number of dozens for each item. For bagels, the cost is $6.99 x 7 = $48.93. For muffins, the cost is $7.50 x 5 = $37.50. Adding these two costs together, we get $48.93 + $37.50 = $86.43, which is more than $75. Therefore, this combination is not reasonable within the given budget.Rate this question:
