Examples of 10th and 11th Grade Math Exercises
Here are a few examples of 10th and 11th grade math exercises, with solutions and explanations:
- Solve for x: 3x + 4 = 16
Solution: To solve for x, subtract 4 from both sides of the equation, which gives us 3x = 12. Divide both sides of the equation by 3, which gives us x = 4.
- Find the area of a triangle with a base of 8 cm and a height of 10 cm.
Solution: The formula for the area of a triangle is A = 1/2bh, where b is the base and h is the height. Plugging in the given values, the area is A = 1/2(8)(10) = 40 cm2.
- Find the slope of the line y = 5x + 7
Solution: To find the slope, use the formula m = (y2 – y1)/(x2 – x1). In this case, y2 = 5x + 7 and y1 = 0, so m = (5x + 7 – 0)/(x2 – x1). Simplifying, m = 5x + 7, which is the slope
