What is the value of 3 x 5?

The value of 3 x 5 is 15.

Solve the equation 2x + 4 = 16.

The solution to the equation 2x + 4 = 16 is x = 6. Subtract 4 from both sides of the equation to isolate the variable, then divide by 2 to solve for x.

Calculate the perimeter of a rectangle with sides measuring 8 cm and 12 cm.

The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, the sides measure 8 cm and 12 cm, so the perimeter would be 8 cm + 8 cm + 12 cm + 12 cm = 40 cm. Hence, the perimeter of the rectangle is 40 cm.

Evaluate the expression 5 + (2 x 3) - 4.

The expression 5 + (2 x 3) - 4 simplifies to 5 + 6 - 4, which further simplifies to 11 - 4, resulting in a final answer of 7.

Find the area of a triangle with a base of 10 cm and a height of 6 cm.

To find the area of a triangle, you can use the formula: Area = 0.5 * base * height. Plugging in the values given, the area of the triangle with a base of 10 cm and a height of 6 cm would be: 0.5 * 10 cm * 6 cm = 30 square cm. Thus, the area of the triangle is 30 square cm.

Simplify the fraction 4/8.

The fraction 4/8 simplifies to 1/2 when reduced to its simplest form by dividing both the numerator and denominator by their greatest common factor, which in this case is 4.

Solve the equation 2/5x = 12.

To solve the equation 2/5x = 12, we need to isolate the variable x. Start by multiplying both sides of the equation by 5 to get rid of the denominator: 5 * (2/5)x = 5 * 12, which simplifies to 2x = 60. Then, divide both sides by 2 to solve for x, yielding x = 30. Therefore, the solution to the equation 2/5x = 12 is x = 30.

Find the value of x in the equation 3x + 7 = 22.

To find the value of x in the equation 3x + 7 = 22, you first subtract 7 from both sides to isolate the term with x. This gives you 3x = 15. Then, divide both sides by 3 to solve for x, which gives you x = 5. Therefore, the value of x in the equation is 5.

Calculate the volume of a cube with side length 5 cm.

The volume of a cube is calculated by cubing the length of one of its sides. In this case, a cube with a side length of 5 cm would have a volume of 5 cm * 5 cm * 5 cm = 125 cubic cm.

Determine the mean of the numbers 5, 6, 8, 9, and 12.

To determine the mean of the numbers 5, 6, 8, 9, and 12, you would add up all the numbers (5+6+8+9+12=40) and then divide by the total count of numbers (5 in this case), resulting in a mean of 8.
