Q: How are algebraic expressions used in measurements?

Algebraic expressions are used to express the length and breadth of an object, such as a rectangular box, in terms of its height. For example, if the height is H centimeters, the length would be 5H centimeters and the breadth would be 5H - 10 centimeters.

Q: How are algebraic expressions used in games?

In games, algebraic expressions can be used to describe relationships between different variables. For example, if Tony has 8 times the number of marbles in his box as the marbles on the table, we can express this as the number of marbles in the box being 8 times the number of marbles on the table.

Q: How are algebraic expressions used in age calculations?

Algebraic expressions are used to calculate ages. For example, if Sarita's present age is y years, her age five years from now would be y + 5. Similarly, if Sarita's grandfather is six times her age, his age can be expressed as 6y.

Q: How are algebraic expressions used to describe relationships between family members' ages?

Algebraic expressions can describe relationships between family members' ages. For example, if Sarita's grandmother is two years younger than her grandfather, her grandmother's age can be expressed as 6y - 2. Similarly, if Sarita's father is five years more than three times her age, his age can be expressed as 3y + 5.

Summary & Key Takeaways

• Algebraic expressions are used in measurements, such as expressing the length and breadth of a rectangular box in terms of its height.

• In games, algebraic expressions are used to describe the relationship between the number of marbles on the table and the number of marbles in a box.

• Algebraic expressions are also used to calculate ages, such as determining Sarita's age five years from now and the ages of her grandparents and father.
