Suppose y varies directly with x if y=27 when x=3 what is y when x=5

The value of y when x = 5 is 45

Given that y varies directly with x. This can be written mathematically as:

y  ∝  x

 ---- eqn 1

Where "k" is the constant of propotionality

Given y = 27 when x = 3. Substitute these values in eqn 1

Substitute k = 9 in eqn 1

y = 9x ----- eqn 2

To find: y = ? and x = 5

Substitute x = 5 in eqn 2

Thus the value of y when x = 5 is 45

john got lost so he didn't know what to do and it was crazy because he didn't except it

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
