The equation would be y=-6x/5 +19 I think
The correct answer is m=x/3k-n
Answer: 
Step-by-step explanation:
Given: Density of tank = 0.4 fish over feet cubed.
We know that, 
Therefore,

Hence, the volume of the tank = 
X=is the number looked for.
x/2=is the half of "x".
x/3=is the one-third of the "x".
We suggest this equation:
x+(x/2)+(x/3)=22
Least common multiple=6
6x+3x+2x=132
11x=132
x=132/11=12
Te number is 12
To check:
A number (12)+ half of that number (6)+ the one-htird of that number(4) is:22
12+6+4=22
31-62=152+2-6(3+21)
31-62=152+2-18+126
-31 =262
