Best Answer

Suppose y = c*x where c is the constant of proportionality.

x = 3 and y = 30 so 30 = c*3 which implies that c = 10.

So the equation is y = 10*x

Q: What direct variation equation relates x and y when x is 3 and y is 30?

The math equation to calculate the amount of money after 30 days with a penny doubling daily can be expressed as: Amount = 0.01 * (2^30) In this equation, "2^30" represents 2 raised to the power of 30 (i.e., doubling daily for 30 days). The result will give you the amount of money accumulated after 30 days.

The answer depends on WHAT the equation is about.

(5x5)+(4+1)=30 :)

95-30%, use this equation; 95.00 x .7 = 66.5

A direct variation is when the value of K in multiple proportions is all divisible by the same number for example: XY=(1)(10) K=10 XY=(2)(20) K=40 XY=(3)(30) K=90 XY=(4)(40) K=160 In this situation the constant (K) of each proportion is divisible by 10 making the multiple equations a direct variation.
