Answer:
w
z = ------------
h - 6k²
Step-by-step explanation:
w = zh - 6zk²
zh - 6zk² = w
w
z = ------------
h - 6k²
The answer is y=3x-4 and here are the steps
It is easier (for me anyway) to find 10% then work around that.
Following that path would mean that, by making a table:
100% = 220
10% = 22
5% (Which is half the 10) = 11
Y equals 15, u have to set them equal to each other which will give u x=9, then plug in x for the top equation
