Introduction to Variation: Direct Variation: When one quantity increases, the other also increases. Formula: y = kx, where k is a constant. Example: If y = 10 when x = 2, find y

## Change of Subject in Mathematics

Change of Subject in Mathematics  To make ‘r’ the subject of the formula in v = πr², you divide both sides by π and then take the square root of both sides. So, r = √(v/π). To make ‘b’ the subject of the formula in A = 1/2bh, you multiply both sides by 2 and

## Understanding Perimeter, Area, and Volume: Essential Maths Concepts for JSS 2 Students

Essential Maths Textbook Page 207, no 21-30 (show workings) Theory page 208 no 6-15       Page 207, Problems 21-30: Problem: Solve for x: 3x + 7 = 22. Solution: Subtract 7 from both sides: 3x = 22 – 7 = 15. Divide both sides by 3: x = 15 / 3 = 5.
