Fill in the blanks.
(i) The solution of the equation ax + b = 0 is_______.
(ii) The shifting of a number from one side of an equation to other is _______.
(iii) If a and b are positive integers then the solution of the equation ax = b has to be always _______.
(iv) Linear equation in one variable has only one variable with power _______.

(i) (ii) (iii) (iv)
A x = b/a commutativity positive 1
B x = –b/a commutativity negative 2
C x = b/a transposition negative 2
D x = –b/a transposition positive 1


Ans 1: (Master Answer)

Class : Class 1

(D): (i) We have, ax + b = 0
⇒ ax = – b 


(ii) The shifting of a number from one side of an equation to other is called transposition.
(iii) We have, ax b
⇒  which is the required solution
Given that a and b are positive integers.
∴ Solution of the equation ax = b has to be always positive.
(iv) Linear equation is of the form ax + = 0 i.e., only one variable with power 1.

A is the correct awnser@

Ans 2:

Class : Class 6

Ans 3:

Class : Class 8
It should be A

Ans 4:

Class : Class 8
it will be athe 5 dots is on the side and the 3 side toothe 1 side will face up if the 2 side is facing at bottom

Ans 5:

Class : Class 6
It should be 5 dots, as we know that the dots on opposite sides add up to 7. But, even if we go according to the figures given, it is clearly 1 dot.

Ans 6:

Class : Class 6
The opposite sides of the dice when added are 7 so if 2 dots are at the bottom 5 dots should be on the top.

Ans 7:

Class : Class 7
Both A and B is correct as it depends that that how the Dice is tilted with 5 dots on upper side

Ans 8:

Class : Class 8
logically 1 will be up so its a not b

Ans 9:

Class : Class 8
the answer is a but it is written b

Ans 10:

Class : Class 7
it will be a

THE CORRECT ANSWER IS ANSWER OPTION C BECAUSE MMMMDCCCI=4701 AND MMMMDCCCI=4801. So ,4701+4801=9502. Some people say that a roman numeral cant be repeated more than 3 times but in fact ( in rare cases )they can be used more than 3 times. like 4000 IS WRITTEN AS MMMM. THANK YOU FOR READING THIS !

Ans 4:

Class : Class 9
Reason is that the rule is that we can't repeat a symbol more than 3 times

Ans 5:

Class : Class 8
c 9502
