You can put this solution on YOUR website!
inverse variation formula is t = k / p
\n" ); document.write( "when t = 5 and p = 7, formula becomes 5 = k / 7
\n" ); document.write( "solve for k to find k = 35.
\n" ); document.write( "that's your constant of variation.
\n" ); document.write( "it is solved for from the given values of t and p.
\n" ); document.write( "if you are given a new value to t, it is used to solve for p.
\n" ); document.write( "if you are given a new value to p, it is used to solve for t.
\n" ); document.write( "if you are given two new values for both t and p, then a new value of k is solved for.
\n" ); document.write( "in this problem you are given a new value for p and asked to solve for t.
\n" ); document.write( "when p = 10, formula becomes t = 35 / 10
\n" ); document.write( "solve for t to get t = 3.5
\n" ); document.write( "that's your answer.\r
