Sample Questions from the Orleans Hanna Algebra Prognosis Test
Below are some sample questions that reflect the style and substance of the Orleans Hanna Algebra Prognosis Test. These questions cover a range of topics commonly found on the test.
1. Multiple-Choice Questions
Question 1: What is the value of \( x \) in the equation \( 3x + 5 = 20 \)?
A) 5
B) 10
C) 15
D) 20
Question 2: Which of the following expressions is equivalent to \( 2(x + 3) - 4 \)?
A) \( 2x + 6 - 4 \)
B) \( 2x + 2 \)
C) \( 2x + 8 \)
D) \( 2x - 1 \)
Question 3: If \( f(x) = 2x^2 + 3 \), what is \( f(2) \)?
A) 7
B) 14
C) 10
D) 12
2. Open-Ended Questions
Question 4: Solve the equation \( 4x - 7 = 13 \) and explain each step in your solution.
Answer:
1. Start with the equation: \( 4x - 7 = 13 \).
2. Add 7 to both sides: \( 4x = 20 \).
3. Divide both sides by 4: \( x = 5 \).
Question 5: Explain how you would determine if the equation \( y = 2x + 3 \) is a function. Provide reasoning for your answer.
Answer:
To determine if an equation represents a function, we check if each input (x-value) has exactly one output (y-value). In the equation \( y = 2x + 3 \), for every x, there is a unique y calculated by multiplying x by 2 and adding 3. Thus, it is a function.
3. Word Problems
Question 6: A rectangle has a length that is 3 times its width. If the perimeter of the rectangle is 48 units, what are the dimensions of the rectangle?
Answer:
Let the width be \( w \). Then the length is \( 3w \).
The perimeter \( P \) is given by the formula:
\[ P = 2(length + width) \]
So:
\[ 48 = 2(3w + w) \]
\[ 48 = 2(4w) \]
\[ 48 = 8w \]
Dividing both sides by 8 gives:
\[ w = 6 \]
Thus, the dimensions are:
- Width = 6 units
- Length = \( 3 \times 6 = 18 \) units
Question 7: If a car travels 60 miles per hour, how long will it take to travel 180 miles?
Answer:
Using the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
We have:
\[ \text{Time} = \frac{180 \text{ miles}}{60 \text{ miles per hour}} = 3 \text{ hours} \]
