6. Using variable and numbers , write an expression :

Sunita is half the age of her mother Geeta. Find their ages before 3 years.

7. Which of the following equations has x = 4 as a
solution?




x + 2 = 5


x – 2 = 0


2x +1 = 0


x + 1 = 5


2x – 6 = 2

Answer 1

Answer:

1. The perimeter of an equilateral triangle, if side of the triangle is m

$p = 3 \times m$

2. Multiple of 5

$x = 5 \times y$

3. If a notebook costs t and a pencil costs Rs. 3, then the total cost (in Rs.) of two notebooks and one pencil.

$x = 2t + 3$

4. 6 times q is subtracted from the smallest two digit number

$x = 9 - 6q$

5. A class with p students has planned a picnic. Rs. 50 per student is collected. From this money Rs.1800 is paid in advance for transport.

money is left with them to spend on other items

$x = 1800 - 50 \times p$

7. x = 4 as a solution by the following equations

x + 1 = 5

x + 1 = 52x – 6 = 2
