    The student begins with 500 rupees in her savings bank account. Every month, she receives an additional 150 rupees as pocket money. At the end of the first month, she will have 650 rupees. After the second month, she will have 800 rupees and the amount will continue increasing regularly. If n represents the number of months, then the total amount after n months can be written as 500 plus 150n rupees. This is a linear expression because the increase is constant every month.

  2. The area of a rectangle is calculated by multiplying its length and breadth. Here, the length is fixed at 13 cm. When the breadth is 12 cm, the area becomes 13 multiplied by 12, which equals 156 square cm. For breadth 10 cm, the area becomes 130 square cm and for breadth 8 cm, the area becomes 104 sRead more

When the breadth is 12 cm, the area becomes 13 multiplied by 12, which equals 156 square cm. For breadth 10 cm, the area becomes 130 square cm and for breadth 8 cm, the area becomes 104 square cm. If the breadth is represented by b, then the linear expression for the area of the rectangle is 13b square cm.

  3. At the beginning, the rally has 120 members. Every hour, 9 members drop out of the group. After 1 hour, the number becomes 111. After 2 hours, it becomes 102 and the decrease continues regularly. If n represents the number of hours, then the number of members remaining after n hours can be written aRead more

    At the beginning, the rally has 120 members. Every hour, 9 members drop out of the group. After 1 hour, the number becomes 111. After 2 hours, it becomes 102 and the decrease continues regularly. If n represents the number of hours, then the number of members remaining after n hours can be written as 120 minus 9n. This expression forms a linear pattern because the number of members decreases by the same amount every hour.

For height 5 cm, the volume becomes 7 multiplied by 11 multiplied by 5, which equals 385 cubic cm. For heights 9 cm and 13 cm, the volumes become 693 cubic cm and 1001 cubic cm respectively. If the height is represented by h, then the linear expression for the volume of the box is 77h cubic cm.

  5. Sarita has a book containing 500 pages and reads 20 pages every day. In 15 days, she reads 20 multiplied by 15, which equals 300 pages. Therefore, the number of pages left becomes 500 minus 300, which equals 200 pages. If n represents the number of days, then the number of pages remaining can be wriRead more
