Answer: 3(x+9) = 12
Step-by-step explanation:
you can set up the equation as 3(x+9) = 12, since sum of x+9 multiply by 3 will equal 12, therefore you have that equation.
To solve for x:
3(x+9) = 12
x+9 = 4
x = -5

Answer:
Answer explained below
Step-by-step explanation:
Let a be the working hours of plant A.
Let b be the working hours of plant H.
Let c be the working hours of plant M.
We have to minimize , Z = 60a + 92b + 140c
subject to constraint , 40a + 20b + 40c >=350
20a + 40b + 40c >=240
where a>=0 , b>=0 ,c>=0
So ,by solving this , a = 7.67 , b= 2.17 , c = 0
So ,working hours of plant A = 8 hrs
working hours of plant H = 3 hrs
working hours of plant M = 0 hrs
