varies how?
either y = kx or xy = k.
Your choice.
Questions an answer
you first find the constant then divide the both variables to get your relationship
You first find the two constant and your two constant will represent the equation
The formula connecting x and y is 5/2 which is x=5/2y
It will be x varies y = 30 therefore it is equal to 30÷12 then it will be 5\2 so the formula is division
It easy
If x× y and x =30 when y =12 .find
A the formular connection x and y
B x when y =10
C y when x =14
The formula connecting x and y is 5 equal to 5/2n or n/2
