Best ResponseYou've already chosen the best response.0i know to do it , its just the decimals get me confused. 2/3 is what? then whatver that is i just multiply it by 13

Best ResponseYou've already chosen the best response.1As z is inversely proportional to x. Then z=k/x substitute the values of z and k and find the value of k

Best ResponseYou've already chosen the best response.0you don't have to divide Z = k/ z substitute z and k values and x is dividing by k so you need to do opposite of division

Best ResponseYou've already chosen the best response.1After finding the value of k, let z=k/x. Then substitute the value of k u found and the other value of k, solve it further and you'll get the answer :)

Best ResponseYou've already chosen the best response.0k is constant of variation first you need to solve for k \[\huge\rm \color{reD}{z}=\frac{ k }{ \color{blue}{x} }\] \[\color{ReD}{z =2}~~~~\color{blue}{x=3}\]

Best ResponseYou've already chosen the best response.0yes k=6 now use the same formula substitute k and z values solve for z

Best ResponseYou've already chosen the best response.0no you need to find z when x =13 this is 2nd part so substitute 13 for x

Best ResponseYou've already chosen the best response.0no u need to find z so it should be z =6/13

Best ResponseYou've already chosen the best response.0i need one more The variable Z is directly proportional to X, and inversely proportional to Y. When X is 6 and Y is 3, Z has the value 6. What is the value of Z when X = 10, and Y = 8

Best ResponseYou've already chosen the best response.0directly proportional = y =kx multiply k with x inverse = y = k/x divide k by x so translate that into the equation

Best ResponseYou've already chosen the best response.0The variable Z is directly proportional to X z= kx and 2nd part is inversely proportional to Y so z =kx/y

Best ResponseYou've already chosen the best response.0When X is 6 and Y is 3, Z has the value 6. this is first part you need to find k value first ALWAYS!
