What is the value of the variable in the equation 3x + 5 = 23?

To find the value of the variable x, you would first isolate the variable by subtracting 5 from both sides of the equation, which gives you 3x = 18. Then, divide both sides by 3 to solve for x, resulting in x = 6. Hence, the value of the variable x in the equation 3x + 5 = 23 is 6.

Solve the inequality 2x - 7 < 13 for x.

To solve the inequality 2x - 7 < 13 for x, you would first add 7 to both sides to get 2x < 20. Then, divide both sides by 2 to get x < 10. Therefore, the solution for x is x < 10.

Find the area of a triangle with a base of 6 cm and a height of 8 cm.

The area of a triangle can be calculated using the formula 1/2 * base * height, where the base is 6 cm and the height is 8 cm. Substituting these values into the formula, we get 1/2 * 6 cm * 8 cm = 24 square cm. Therefore, the area of the triangle is 24 square cm.

Simplify the expression 5(2x - 3) - 2(4x + 1).

To simplify the expression 5(2x - 3) - 2(4x + 1), first distribute the 5 and 2 to the terms inside the parentheses. This gives us 10x - 15 - 8x - 2. Combining like terms, we get 2x - 17 as the simplified expression.

A store is having a 20% off sale. If a shirt is originally $25, what is the sale price?

The sale price of the shirt would be $20 after a 20% discount is applied ($25 - 20% of $25).

What is the slope of a line that passes through the points (-2, 4) and (5, 7)?

To find the slope of a line passing through two points (x1, y1) and (x2, y2), you can use the formula: slope = (y2 - y1) / (x2 - x1). Substituting the coordinates (-2, 4) and (5, 7) into the formula, the slope of the line passing through these points is (7 - 4) / (5 - (-2)) = 3 / 7. Hence, the slope of the line is 3/7.

Solve the equation 4(x + 3) = 20 for x.

To solve the equation 4(x + 3) = 20 for x, first distribute the 4, which gives you 4x + 12 = 20. Next, subtract 12 from both sides of the equation to isolate the variable x, resulting in 4x = 8. Finally, divide by 4 on both sides to solve for x, giving you x = 2. So, the solution to the equation is x = 2.

Find the volume of a rectangular prism with a length of 10 cm, width of 5 cm, and height of 3 cm.

The volume of a rectangular prism is calculated by multiplying its length, width, and height. Therefore, for a rectangular prism with a length of 10 cm, width of 5 cm, and height of 3 cm, the volume would be 10 cm x 5 cm x 3 cm = 150 cubic centimeters.

Simplify the expression 2a^2 + 3a^2 - 4a^2 + 5a^2.

When combining like terms, the expression simplifies to 6a^2.

Find the missing side length of a right triangle with one leg measuring 6 cm and a hypotenuse of 10 cm.

Using the Pythagorean theorem (a^2 + b^2 = c^2), where a and b are the legs of a right triangle and c is the hypotenuse, we can find the missing side length. Given that one leg is 6 cm and the hypotenuse is 10 cm, we can plug in the values into the equation: 6^2 + b^2 = 10^2. Solving for b, we get 36 + b^2 = 100. Subtracting 36 from both sides gives us b^2 = 64. Taking the square root of both sides, b = 8 cm. Therefore, the missing side length of the right triangle is 8 cm.
