Assume the shorter piece of the fence is x feet long. Since the longer piece is four times the shorter piece, its length becomes 4x feet. The total length of the fence is 300 feet, so we form the equation x plus 4x equals 300. This simplifies to 5x equals 300. Dividing both sides by 5 gives x equalRead more

Suppose the width of the rectangle is x cm. According to the question, the length is three more than twice the width, so the length becomes 2x plus 3 cm. The perimeter of a rectangle is 2 multiplied by length plus width and it is given as 24 cm. Therefore, 2 multiplied by 2x plus 3 plus x equals 24.Read more
Suppose the width of the rectangle is x cm. According to the question, the length is three more than twice the width, so the length becomes 2x plus 3 cm. The perimeter of a rectangle is 2 multiplied by length plus width and it is given as 24 cm. Therefore, 2 multiplied by 2x plus 3 plus x equals 24. Simplifying gives 6x plus 6 equals 24, so x equals 3. Hence, the width is 3 cm and the length is 9 cm.

The growing pattern of square tiles forms a sequence where each stage has 2 more squares than the previous stage. The first four stages contain 1, 3, 5 and 7 squares. Continuing this pattern, the next three stages will contain 9, 11 and 13 squares respectively. Therefore, the complete sequence from Stage 1 to Stage 7 becomes 1, 3, 5, 7, 9, 11 and 13. This is called a linear pattern because the increase between consecutive terms remains constant.

A farmer cuts a 300 feet fence into two pieces of different sizes. The longer piece is four times as long as the shorter piece. How long are the two pieces?
Assume the shorter piece of the fence is x feet long. Since the longer piece is four times the shorter piece, its length becomes 4x feet. The total length of the fence is 300 feet, so we form the equation x plus 4x equals 300. This simplifies to 5x equals 300. Dividing both sides by 5 gives x equalRead more
