Question

Write the following statements in algebraic form.

A. A number decreased by 3 and then doubled.
B. A number is tripled and then increased by 8.
C. Area of rectangle is the product of its length and breadth.
D. Product of two numbers divided by 3.
E. x is halved and increased by 11

Answer 1

a= 2 ( n-3 )

b= 3 ( x+8 )

c= x= l×b

d= x/3

e= x/2 + 11

Answer 2

A) A number decreased by 3 and then doubled.

= 2 ( n-3 )

B. A number is tripled and then increased by 8.

= 3 ( x+8 )

C. Area of rectangle is the product of its length and breadth.

x= l×b

D. Product of two numbers divided by 3.

= x/3

E. x is halved and increased by 11

= x/2 + 11
