Which equation describes the relationship between x and y in the table above?
- A.
Y = y + 5
- B.
Y = 2x - 5
- C.
Y = 5x - 2
- D.
Y = x + 2
Correct Answer
C. Y = 5x - 2Explanation
The equation y = 5x - 2 describes the relationship between x and y in the table. This equation shows that y is equal to 5 times x minus 2. This means that as x increases, y will increase at a rate of 5 times the increase in x, with a constant decrease of 2.Rate this question:

The width and length, in feet, of a rectangular playground are x and x + 2. A fence costs $17 per foot. Write an expression to show the distance around the playground.
- A.
X ( x + 2)
- B.
X +( x + 2 )+ x +( x + 2)
- C.
X - x (2)
- D.
X + 17 (x + 2)
Correct Answer
B. X +( x + 2 )+ x +( x + 2)Explanation
The expression x +( x + 2 )+ x +( x + 2) represents the distance around the playground. The first x represents one side of the playground, the second x + 2 represents the adjacent side, and the two additional terms represent the other two sides. By adding all these terms together, we get the total distance around the playground.Rate this question:

The width and length, in feet, of a rectangular playground are x and x + 2. A fence costs $17 per foot. What is the expression for the cost of the fence?
- A.
17[x + (x + 2)]
- B.
17x(x + 2)
- C.
17[x + (x + 2) + x + (x + 2)]
- D.
17 + x + (x + 2)
Correct Answer
C. 17[x + (x + 2) + x + (x + 2)]Explanation
The expression for the cost of the fence is 17[x + (x + 2) + x + (x + 2)]. This can be derived by multiplying the cost per foot ($17) by the total perimeter of the rectangular playground. The perimeter is calculated by adding the lengths of all four sides of the rectangle, which in this case is x + (x + 2) + x + (x + 2).Rate this question:

The width and length, in feet, of a rectangular playground are x and x + 2. A fence costs $17 per foot and the total cost for the fence was $1,428. What is the value of x?
- A.
20
- B.
84
- C.
2
- D.
8
Correct Answer
A. 20Explanation
The total cost for the fence is given as $1,428, and the cost per foot is $17. To find the value of x, we need to determine the perimeter of the rectangular playground. The perimeter of a rectangle is calculated by adding up all four sides. In this case, we have two sides of length x and two sides of length x + 2. Therefore, the perimeter is 2x + 2(x + 2) = 4x + 4. The cost of the fence is equal to the perimeter multiplied by the cost per foot, so we have the equation 17(4x + 4) = 1428. Solving for x, we find that x = 20.Rate this question:

A fence costs $17 per foot and the total cost for the fence was $1,428. How many feet of fence were purchased?
- A.
20
- B.
84
- C.
8
- D.
17
Correct Answer
B. 84Explanation
The total cost of the fence is given as $1,428 and the cost per foot is $17. To find the number of feet of fence purchased, we need to divide the total cost by the cost per foot. Therefore, $1,428 / $17 = 84. Hence, 84 feet of fence were purchased.Rate this question:
