What is the result of 3 × (4 + 2) − 8?
Answer: 10
Explanation: Follow the order of operations: first, perform the operation inside the parentheses, then multiplication, and finally subtraction.
What is the perimeter of a rectangle with a length of 8 meters and a width of 5 meters?
Answer: 26 meters
Explanation: The perimeter of a rectangle is calculated by adding all four sides. For this rectangle: Length = 8 meters Width = 5 meters Perimeter = 2*(Length + Width) = 2*(8 + 5) = 2*(13) = 26 meters
Solve for x in the equation 2x + 5 = 13.
Answer: 4
Explanation: To solve the equation 2x + 5 = 13: Subtract 5 from both sides: 2x = 13 − 5 2x = 8 Now, divide both sides by 2 to solve for x: x = 8/2 x = 4
If x = 7, what is the value of 2x − 3?
Answer: 11
Explanation: If x = 7, we can substitute this value into the expression 2x − 3 and calculate the result: 2x − 3 = 2 (7) − 3 = 14−3 = 11
What is the next number in the sequence: 2, 5, 8, 11, ...?
Answer: 14
Explanation: To find the next number in the sequence, we observe that each number is increasing by 3: 2, 5, 8, 11,... So, to find the next number, we add 3 to the last number in the sequence: 11 + 3 = 14
If a rectangle has a length of 10 units and a width of 4 units, what is its area?
Answer: 40 square units
Explanation: To find the area of a rectangle, multiply its length by its width. Given: Length = 10 units Width = 4 units Area = Length × Width = 10 units × 4 units = 40 square units
Solve for x in the equation 3 (x − 2) = 15.
Answer: 7
Explanation: To solve the equation 3 (x − 2) = 15, follow these steps: Distribute the 3 to both terms inside the parentheses: 3 × X − 3 × 2 = 15 3x − 6 = 15 Add 6 to both sides of the equation: 3x − 6 + 6 = 15 + 6 3x = 21 Divide both sides by 3 to isolate x: 3𝑥/3 = 21/3 x = 7
What is the volume of a cube with a side length of 4 units?
Answer: 64 cubic units
Explanation: To find the volume of a cube, you raise the length of one side to the power of 3. Given: Side length = 4 units Volume = Side length × Side length × Side length = 4 units × 4 units × 4 units = 64 cubic units
If a car travels at a speed of 60 miles per hour, how far will it travel in 2.5 hours?
Answer: 150 miles
Explanation: To find the distance traveled, we multiply the speed (rate) by the time traveled. Given: Speed = 60 miles per hour Time = 2.5 hours Distance = Speed × Time Distance = 60 miles/hour × 2.5 hours Distance = 150 miles
What is the mode of the following set of numbers: 5, 8, 5, 2, 7, 5, 4, 9?
Answer: 5
Explanation: The mode of a set of numbers is the number that appears most frequently. Given the set of numbers: 5, 8, 5, 2, 7, 5, 4, 9 The number 5 appears three times, which is more than any other number in the set.
What is the value of 15 − 3× (4 + 2)?
Answer: 3
Explanation: To solve the expression 15 − 3 × (4 + 2), follow the order of operations (PEMDAS/BODMAS): Perform the operation inside the parentheses: 4 + 2 = 6 Multiply: 3 × 6 = 18 Subtract: 15 − 18 = −3
