Question

Y varies directly as x, y = 35 when x = 5. Find y when x = 12

Answer 1

I don’t know if this is correct or makes sense but I think it would be y=84
If 5:35
Which means when x=1 y=5
Soo..you multiply x•5 to get y
IE; 12•5=84

Answer 2

The value of y when (x = 12) is 84 and this can be determined by forming the linear equation with the help of the given data.

Given :

• y varies directly as x
• y = 35 when x = 5

The following steps can be used to determine the value of y when x = 12:

Step 1 - Given that y varies directly as x, that means:

$\rm y \; \alpha \; x$

Step 2 - The above expression becomes:

y = kx   ----- (1)

Step 3 - Given that y = 35 when x = 5, that implies:

35 = 5k

k = 7

Step 4 - Put the value of k in equation (1).

y = 7x

Step 5 - Now, the value of y when x = 12 is:

y = 7(12)

y = 84

So, the value of y when (x = 12) is 84.
