Answer:
Country A = 85, Country B = 29, Country C = 20
Step-by-step explanation:
A+B+C=134 ----- eq(1)
B=C+9 ------------ eq(2)
A=36+B+C ------ eq(3)
By substituting eq(2) in eq(3), we get:
A=36+C+9+C
A=2C+45 ------- eq(4)
Now substituting eq(2) & eq(4) in eq(1), we get
2C+45+C+9+C=134
4C+54=134
4C=134-54
4C=80
C=20
Now putting the value of C in eq(2),
B=20+9
B=29
Substituting the value of B & C in eq(1), we get:
A+29+20=134
A+49=134
A=134-49
A=85
When you convert each type of ribbon to a bigger fraction, you get 32/6 feet of silver ribbon by multiplying the denominator by the whole number then adding the numerator. you also get 16/6 feet of gold ribbon. 32-16=16 so Gina has 16 more feet of silver ribbon than gold

Answer:
The maximum is at (0,4)
Step-by-step explanation:
x≥0
y≥0
x+y ≤4
2x+y ≤6
We need to plot the four inequalities. The left side has no axis. The max is at 4. The minimum is at 0 for the shaded area
When we have a system of constraints, the minimum and maximum are at the vertices of the graph
There are 4 points
(0,0)
The intersection point of the 2 lines which is (2,2)
The intersection at the y axis (0,4)
The intersection at the x axis is (3,0)
Once we have these points we put them into the constraint equation
C = 30x+50y
(0,0)
C = 0+0 = 0 This would be the trivial point since nothing happens
(0,4)
C = 0+50(4) = 200
(3,0)
C = 30*3 = 90
(2,2)
C = 30(2) + 50(2) = 60+100 = 160
The maximum is at (0,4)
