y varies jointly as x and z, and y = 32 m, x = 6 m, and z = 8 m.
What is the value of y when x = 5 m and z = 12 m?

Best ResponseYou've already chosen the best response.1Can you write the joint variation equation for x y and z? Use k for the constant.

Best ResponseYou've already chosen the best response.0so it would be 32m= k *5m*12m

Best ResponseYou've already chosen the best response.1y = kxz we're given y = 32 m, x = 6 m, and z = 8 m plug all this in to get 32 = k*6*8 now solve for k Note: I think we can ignore the m's because I think they refer to meters (eg: x = 6 m means x is 6 meters long)

Best ResponseYou've already chosen the best response.132 = k*6*8 32 = k*48 k = ??

Best ResponseYou've already chosen the best response.1no it's not 4 divide both sides by 48 to solve for k

Best ResponseYou've already chosen the best response.1more like 0.667 but I would keep it as a fraction so k = 2/3

Best ResponseYou've already chosen the best response.1y = kxz y = (2/3)xz y = (2/3)*5*12 plug in x = 5 and z = 12 y = ???

Best ResponseYou've already chosen the best response.0my choices are 90m, 4m, 40m, 9m

Best ResponseYou've already chosen the best response.1now multiply that by 2 then divide that result by 3
