Answer:
Least cost per kilogram is "$5 for 2.0 kg"
Step-by-step explanation:
To get cost per kilogram, we divide the cost given by the kg given.
1. We need to divide 4 by 1.5 to get cost per kilogram.
Cost/Kg = 
2. We need to divide 5 by 2.0 to get cost per kilogram.
Cost/Kg = 
3. We need to divide 7 by 2.5 to get cost per kilogram.
Cost/Kg = 
4. We need to divide 8 by 2.5 to get cost per kilogram.
Cost/Kg = 
As we can see, the second option costs the least per kilogram.
Y = 2x - 4....so sub in 2x - 4 for x in the other equation
y = x^2 - 6x + 12
2x - 4 = x^2 - 6x + 12
x^2 - 6x - 2x + 12 + 4 = 0
x^2 - 8x + 16 = 0
(x - 4)(x - 4) = 0
x - 4 = 0
x = 4
x - 4 = 0
x = 4
solution is (4,4)
A) x = 0.296
B) x= 15
Step-by-step explanation:
Step 1:
(2/3) : x :: 4.5 :2
By using expansion method,
(2/3) × 2 = 4.5 x
x= (2/3) × 2 / 4.5
x = 0.296
Step 2:
(2/3) : (1/5) :: 50 :x
By using expansion method,
(2/3) x = (1/5) × 50
x= (1/5) × 50 / (2/3)
x = 15
Answer:
12 x 9 = 108
