What is the simplified form of 1/2 + 1/3?
5/6
2/3
3/5
1/2
To add 1/2 and 1/3, find the common denominator, which is 6, then convert the fractions to get 3/6 and 2/6 respectively. Adding these gives 5/6.
Solve the equation: x + 7 = 12. What is the value of x?
17
12
5
7
Subtracting 7 from both sides of the equation gives x = 5. This is the basic method for solving simple linear equations.
What is the simplified form of the fraction 20/30?
2/3
3/5
1/2
4/5
Both 20 and 30 can be divided by 10, giving 2/3 after simplification. This is the simplest form of the fraction.
What is the perimeter of a rectangle with a length of 5 units and a width of 3 units?
16
15
18
8
The perimeter of a rectangle is calculated using the formula 2 Ã - (length + width). Here, 2 Ã - (5 + 3) equals 16.
If you have $50 and spend 20% of it, how much money did you spend?
$20
$10
$5
$15
Twenty percent of $50 is calculated by multiplying 50 by 0.20, which equals $10. This shows a basic understanding of percentages.
Solve for x: 3x - 5 = 16.
8
6
5
7
Add 5 to both sides to get 3x = 21, then divide both sides by 3 to find x = 7. This is a straightforward linear equation problem.
If y = 2x + 3, what is the value of y when x = 4?
10
11
8
9
Substitute x = 4 into the equation to get y = 2(4) + 3, which calculates to 11. This tests the ability to evaluate a linear function.
What is the slope of the line passing through the points (1, 4) and (3, 10)?
6
4
3
2
The slope is calculated as the change in y divided by the change in x: (10 - 4) / (3 - 1) equals 3. This demonstrates an understanding of the concept of slope.
Simplify the expression: 2(3x - 4) + 4x.
8x - 8
10x - 8
10x + 8
8x + 8
Distribute 2 to get 6x - 8, then add 4x to combine like terms, resulting in 10x - 8. This tests the use of the distributive property and combining like terms.
What is the area of a triangle with a base of 8 units and a height of 5 units?
40
25
20
15
The area of a triangle is given by the formula 1/2 à - base à - height. For a base of 8 and a height of 5, the area calculates to 20.
Convert 0.75 to a fraction in simplest form.
4/5
3/4
2/3
1/2
0.75 can be written as 75/100, which simplifies to 3/4 after dividing both numerator and denominator by 25. This question reinforces decimal to fraction conversion.
A bag contains 3 red, 5 blue, and 2 green marbles. What is the probability of drawing a blue marble?
1/5
2/3
1/2
1/3
There are a total of 10 marbles and 5 are blue, so the probability of drawing a blue marble is 5/10, which simplifies to 1/2. This tests basic probability concepts.
Solve the proportion: 5/x = 15/9. What is the value of x?
15
3
5
9
Cross multiplying gives 5 Ã - 9 = 15 Ã - x, which simplifies to 45 = 15x, and therefore x = 3. This problem reinforces the method of solving proportions.
If a number is increased by 50% and then decreased by 50%, what is the final value if the original number was 80?
60
90
80
100
Increasing 80 by 50% gives 120. Reducing 120 by 50% yields 60, showing that percentage increase and decrease are not direct inverses.
What is the perimeter of a square with an area of 49 square units?
14
49
21
28
A square with an area of 49 has a side length of √49 = 7 units. The perimeter is 4 times the side length, so 4 à - 7 equals 28.
Factor completely: x² - 5x + 6.
(x - 3)(x + 2)
(x - 2)(x - 3)
(x - 1)(x - 6)
(x + 2)(x + 3)
The expression factors as (x - 2)(x - 3) because -2 and -3 multiply to 6 and add up to -5. This factorization is a common quadratic factoring technique.
Solve the system of equations: 2x + y = 10 and x - y = 1. What are the values of x and y?
x = 4, y = 3
x = 3, y = 4
x = 11/3, y = 11/3
x = 11/3, y = 8/3
Using substitution from the second equation (y = x - 1) into the first yields 2x + (x - 1) = 10, or 3x = 11, so x = 11/3 and y = 8/3. This tests solving simultaneous linear equations.
What is the circumference of a circle with a radius of 7 units? Express your answer in terms of π.
49Ï€
28Ï€
7Ï€
14Ï€
The formula for the circumference of a circle is 2Ï€r. With a radius of 7, the circumference is 2 Ã - 7Ï€ = 14Ï€.
The sequence is 2, 5, 10, 17, ... What is the next term?
30
26
25
27
Observing the sequence, the nth term seems to follow the pattern n² + 1. For n = 5, this gives 25 + 1 = 26, which is the next term.
What is the volume of a rectangular prism with a length of 4 units, a width of 3 units, and a height of 2 units?
24
14
12
9
The volume of a rectangular prism is calculated by multiplying its length, width, and height: 4 Ã - 3 Ã - 2 = 24. This reinforces spatial reasoning with 3-dimensional figures.
