Suppose the smaller number is x. Since the larger number is 10 more than the smaller number, it becomes x plus 10. According to the question, the sum of the two numbers is 64. Therefore, we form the equation x plus x plus 10 equals 64. This simplifies to 2x plus 10 equals 64. Subtracting 10 gives 2xRead more
Suppose the smaller number is x. Since the larger number is 10 more than the smaller number, it becomes x plus 10. According to the question, the sum of the two numbers is 64. Therefore, we form the equation x plus x plus 10 equals 64. This simplifies to 2x plus 10 equals 64. Subtracting 10 gives 2x equals 54 and dividing by 2 gives x equals 27. Hence, the two numbers are 27 and 37.

The chess club charges a fixed joining fee of 200 rupees. In addition, the player must pay 50 rupees for every match played. If the number of matches played is represented by m, then the total amount paid can be written as 200 plus 50m. This is a linear polynomial because the highest power of the vaRead more
The chess club charges a fixed joining fee of 200 rupees. In addition, the player must pay 50 rupees for every match played. If the number of matches played is represented by m, then the total amount paid can be written as 200 plus 50m. This is a linear polynomial because the highest power of the variable m is 1. The amount paid increases regularly by 50 rupees whenever one more match is played.

Suppose Ruby has x five-rupee coins. Since she has three times as many two-rupee coins, the number of two-rupee coins becomes 3x. The total value of five-rupee coins is 5x rupees and the total value of two-rupee coins is 2 multiplied by 3x, which equals 6x rupees. Therefore, the total amount is 5x pRead more
Suppose Ruby has x five-rupee coins. Since she has three times as many two-rupee coins, the number of two-rupee coins becomes 3x. The total value of five-rupee coins is 5x rupees and the total value of two-rupee coins is 2 multiplied by 3x, which equals 6x rupees. Therefore, the total amount is 5x plus 6x equals 88. Solving gives 11x equals 88, so x equals 8. Hence, Ruby has 8 five-rupee coins and 24 two-rupee coins.
