Question

Please answers this questions Algebra. 5 to 7

Answer 1

5 let myra age b and abhinav a
b=a+4

Answer 2

Hey there!

Sheena here!

So, Solutions >>>

5) Let us take Abhinav's age as x

So the expression for Myra's age will be

x + 4 

Reason >>> Because Myra is four years more than Abhinav.

6) Let the cost of a pen be Rs. y

So the cost of 5 pens will be 5*y = 5y  

So if  Sohal gave a 500 rupees note i.e 500 rupees so the money she will get back will be 

=> 500 - 5y

Note: Here we have to take Rs. 500 first as we need to subtract the cost of pens through that money.

7) Let the minutes be t minutes.

So if Rehaan covers 35m in one minute so the distance covered by him in t minutes will be

   35*t 
= 35t km.
