Question 1175777
inverse variation formula is t = k / p
when t = 5 and p = 7, formula becomes 5 = k / 7
solve for k to find k = 35.
that's your constant of variation.
it is solved for from the given values of t and p.
if you are given a new value to t, it is used to solve for p.
if you are given a new value to p, it is used to solve for t.
if you are given two new values for both t and p, then a new value of k is solved for.
in this problem you are given a new value for p and asked to solve for t.
when p = 10, formula becomes t = 35 / 10
solve for t to get t = 3.5
that's your answer.
