Question 3. Write an algebraic expression for each of the following:

(i) If 1 metre cloth costs ₹ x, then what is cost of 6 metre cloth?
(ii) If the cost of a notebook is ₹ x and the cost of a book is ₹ y, then what is the cost of 5 notebooks and 2 books?
(iii) The score of Ragni in Mathematics is 23 more than two-third of her score in English. If she scores x marks in English, what is her score in Mathematics?
(iv) If the length of a side of a regular pentagon is x cm, then what is the perimeter of the pentagon?

Answer:

(i) Cost of 1 metre cloth = ₹ x
Cost of 6 metre cloth = ₹ x × 6 = ₹6x
(ii) Cost of 1 notebook = ₹ x
Cost of 1 book = ₹y
Cost of 5 notebooks = 5 × (₹x) = ₹5x
Cost of 2 books = (₹y) × 2 = ₹2y
Total cost of 5 notebooks and 2 books = ₹(5x + 2y)
(iii) Score of Ragni in English = x marks
Score of Ragni in Mathematics = 23 more than two-third of her score in English
i.e. = 23 + 2/3x
= 23 + 2/3x
(iv) Side of regular pentagon = x cm
Perimeter of pentagon = 5 × Side = 5x cm

Question 4. When x = 4 and y = 2, find the value of:

(i) x + y
(ii) x – y
(iii) x2 + 2
(iv) x2 – 2xy + y2

Answer:

(i) x + y
Put x = 4 and y = 2
We get,
⇒ 4 + 2 = 6

(ii) x – y
Put x = 4, y = 2
We get,
⇒ 4 – 2 = 2

(iii) x2 + 2
Put x = 4 We get,
⇒ (4)2 + 2
= 16 + 2= 18

(iv) x2 – 2xy + y2
Put x = 4 and y = 2

Question 5.  When a = 3, b = 0, c = -2, find the values of:

(i) ab + 2bc + 3ca + 4abc
(ii) a3 + b3 + c3 – 3abc

Answer:

(i) ab + 2bc + 3ca + 4abc
Put the values of a = 3, b = 0, c = -2
3 × 0 + 2 × 0 × -2 + 3 × -2 × 3 + 4 × 3 × 0 × -2
= 0 + 0 – 18 + 0 = -18

(ii) a3 + b3 + c3 – 3abc
Put the values of a = 3, b = 0, c
= -2 (3)3 + (0)3 + (-2)3 – 3 × 3 × 0 × -2
= 27 + 0 – 8 – 0 = 19

Question 6. Solve the following linear equations:

(i) 2x – 1(1/2) = 4(1/2)
(ii) 3(y – 1) = 2(y + 1)
(ii) n – 3 = 5n + 21
(iv) 1/3 (7x – 1) = 1/4

Answer:

Question 6. Solve the following linear equations:

Question 6. Solve the following linear equations:
