**Algebra – CBSE Class 6 Mathematics/Extra Questions for Practice**

——————————————————————————————–

**Answer the following:**

**‘x multiplied by 10’ can be written as ——————**

Answer: 10x**’10 is added to x’ can be written as —————–**

Answer: 10 + x**If x = 2, find the value of 10x?**

Answer:

10x = 10 x 2 = 20**Perimeter of a square of side length l is —————**

Answer: 4l**If x =3, find the value of 4x + 5?**

Answer:

4x + 5 = 4 x 3 + 5 = 12 + 5 = 17**Write an algebraic expression for: ‘m multiplied by 3 and 2 subtracted from the product’**

Answer: 3m – 2**Find the solution of n – 4 = 100?**

Answer:

n = 100 + 4 = 104**Solve 20b = 80**

Answer:

b = 80/20 = 4**Solve:**

a) 2l + 3 = 7

b) 2m – 3 = 5

c) 3n = 21

Answer:

a) 2l = 7 – 3 = 4

l = 4/2 = 2

b) 2m = 5 + 3 = 8

m = 8/2 = 4

c) n = 21/3 = 7**If m = 3, find the value of 2m – 3?**

Answer:

2m – 3 = 2 x 3 – 3 = 6 – 3 = 3**Write an algebraic expression for: ‘sum of m and n subtracted from their product’**

Answer: mn – (m + n)**‘3 is subtracted from the product of a and b’ can be written as—–**

Answer: ab – 3**Find the general rule which gives the number of matchsticks required to make a pattern of letter Z?**

Answer: 3n**If the length of a side of a regular hexagon is y cm, then its perimeter is ————–**

Answer: 6y**5 times a number is 35. Find the number?**

Answer:

Let the number be y.

Given 5y = 35

y = 35/5 = 7**If x = 2 and y = -1, evaluate 3x – y?**

Answer:

3x – y = 3 x 2 – (-1) = 6 + 1 = 7**If 2x – 3 = 5, then the value of x is ———-**

Answer:

2x = 5 + 3 = 8

x = 8/2 = 4**If you take away 5 from 5 times a number, you get 50. Find the number?**

Answer:

Let the number be y.

5y – 5 = 50

5y = 50 + 5 = 55

y = 55/5 = 11**If a = -1, b = -2, find the value of ab – (a + b)?**

Answer:

ab – (a + b) = (-1) x (-2) – (-1 + -2) = 2 – (-3) = 2 + 3 = 5**If x – 4 = 4, find the value of x?**,

Answer:

x – 4 = 4**x = 4 + 4 = 8**
