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?

Can you write the joint variation equation for x y and z? Use k for the constant.

- Mertsj

y=kxz

Now plug in the given values and find k.

does Mertsj's response make sense?

- anonymous

a little, im still a little confused ..

- anonymous

so it would be 32m= k *5m*12m

- jim_thompson5910

y = 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)

4?

- jim_thompson5910

no

- jim_thompson5910

32 = k*6*8
32 = k*48
k = ??

- anonymous

its 4?

- jim_thompson5910

no it's not 4
divide both sides by 48 to solve for k

- anonymous

0.6?

- jim_thompson5910

more like 0.667
but I would keep it as a fraction so k = 2/3

- jim_thompson5910

y = kxz
y = (2/3)xz
y = (2/3)*5*12 plug in x = 5 and z = 12
y = ???

- anonymous

my choices are 90m, 4m, 40m, 9m

- jim_thompson5910

5*12 is what

- anonymous

60

- jim_thompson5910

now multiply that by 2
then divide that result by 3

- anonymous

4

- jim_thompson5910

close, but not quite

- anonymous

40*

- jim_thompson5910

yep

- anonymous

thank you(:
