Suppose that y varies jointly with w and x and inversely with z and y = 360 when w = 8, x = 25, and z = 5. Write the equation that models the relationship. Then find y when w = 4, x = 4, and z = 3.

y=wx9/z, 48

anonymous · Answer

i did set it up correctly i was simply confused sorry.

smokeysthename · Answer

how did you get that? i dont want just the answer, i need an explanation too

anonymous · Answer

so basically make the equation y=wxc/z we know that wx varies jointly and inversely with z so wx is on top of the fraction and z is on the bottom. There is an unknown factor c we have to solve for. Solving for c after we plug in the values get we get 9. If you need more explanation I can try.
