Answer:
Step-by-step explanation:
Assuming you forgot to write what the 2nd y is equal to, I set it to y = 5 like the first one. I showed work so if that’s not right you can plug in the correct number.
Answer:
k = ⅔
d. y = ⅔xz; y(6, 3) = 12
Step-by-step explanation:
y ∝ x and y ∝ z, so
y ∝ xz and
(1) y = kxz Divide each side by xz
k = y/(xz) Let x = 1, z =4, y = ⁸/₃
= (⁸/₃)/(1 × 4)
= ⁸/₃ × ¼ Cancel 4s
(2) k = ⅔ Substitute into (1)
y = ⅔xz Let x = 6, z = 3
y = ⅔ × 6 × 3 Cancel 3s
y = 2 × 6
y = 12
y(6, 3) = 12

I will come back to it later. I can't delete this answer i'm sorry
Ok so I think what you need to be solved is to find h? So I am gonna do that
To find h the first thing you need to do is get the variable h all on one side. So subtract 6.5h from the right side and subtract 5 from the left side. It will then look like this:
0.75h = 5.25
Now you need to isolate the variable so you must divide both side by 0.75 to get h by itself. This should now look like:
h = 7
So now you know that h is equal to 7
You can always check to see if the answer is correct by plugging in 7 for h on both sides and seeing if they equal the same amount.
Hope this helps :)
