Question 989158


Formula:  {{{R = kg/h^2}}}


Solve by substituting, R = 3 when g = 3 and h = 5.


{{{3 = k(3)/(5)^2}}}



{{{3 = 3k/25}}}


Multiply both sides by 25 to get rid of the fraction:


{{{25*3 = (3k/25)*25}}} ---> {{{75 = 3k}}}


Next, divide 3 on both sides:


{{{75/3 = 3k/3}}}  


{{{k = 25}}}



Therefore, {{{R = 25g/h^2}}} is your general formula.
