Almons:walnuts:rasins=1:2:3
x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute
12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins
1/3 pound walnuts
2/3 pound almonds
1 pound rasins
Answer:
the maximum value is 7
The minimum value is 0
Step-by-step explanation:
Step One : Interpret the question
The above question can be written like
The Equation
The diagram of the triangular plate and the bounded lines is shown on the first uploaded image
From the diagram 


Partial differentiation of the equation w.r.x

Partial differentiation of the equation w.r.y
Looking at the diagram the maximum value is 7 i.e at (x , y) = (0,1)
The minimum value is 0 i.e (x , y) = (0,0)
Well you do 228/12 to find your answer and that is 19 and to check you do 12*19=228
Answer:
5x<12
Step-by-step explanation:
Five times x is equally 5x fewer than is equally < # 5x<12
