Question

extra questions from chapter Linear inequations​

Answer 1

Step-by-step explanation:

Q.1: The cost of 2 kg of apples and 1kg of grapes on a day was found to be Rs.160. After a month, the cost of 4 kg of apples and 2 kg of grapes is Rs.300. Represent the situation algebraically.

Half the perimeter of a rectangular garden, whose length is 4 m more than its width, is 36 m. Find the dimensions of the garden.

On comparing the ratios a1a2, b1b2, and c1c2, find out whether the following pair of linear equations are consistent, or inconsistent.

Solve the following pair of linear equations by the substitution method.

(i) x + y = 14

x – y = 4

(ii) 3x – y = 3

9x – 3y = 9
