Question

someone please answer this correctly please​

Answer 1

Step-by-step explanation:

Solution :-

Given that

x and y vary directly.

We know that

If x is directly proportional to y then

x ∝ y => x/y = K , a constant.

Given that x = 36 and y = 2 then

x/y = 36/2 = 18

Therefore, K= 18

Now,

1) If x = 18 and y = a then

x/y = K

=> 18/a = 18

=> 18 = 18×a

=> a = 18/18

=> a = 1

Therefore, a = 1

and

If x = 54 and y = b then

x/y = K

=> 54/b = 18

=> 54 = 18×b

=> b = 54/18

=> b = 3

Therefore, b = 3

and

If x = c and y = 5 then

x/y = K

=> c/5 = 18

=> c = 18×5

=> c = 90

Therefore, c = 90

Answer :-

The value of a = 1

The value of b = 3

The value of c = 90

Used Concept :-

→ If x is directly proportional to y then

x ∝ y => x/y = K , a constant.
