Answer:
Step-by-step explanation:
as x is direct to y hence
x∝y
also given x∝z combine these two equation we get
x∝y*z
now insert b as constant
x=b*y*z
as given x=20, y=3 , z=4 putt in above equation we get
b=20/3*4 =5/3 =1.666

Answer:
10 hours
Step-by-step explanation:
So what you would do is subtract 10 from 80 because you earn $80 and lose $10 out of that $80 every hour and you would end up with $70 and to find how long it would take to earn $700 is you would divide 700 by 70 and your final awnser would be 10 hours.
2x - 3y = 8
Subtract '2x' to both sides:
-3y = -2x + 8
Divide -3 to both sides:
y = 2/3x + 8/3
or
y = 2/3x + 2 2/3
