Answer: x = 1.32 and x= 0.076
Step-by-step explanation:
4x(5x-2) = 20x-2
20x^2-8x = 20x-2
20x^2-8x-20x+2=0
20x^2-28x+2=0
Using quadratic equation
x = (-b +or- √(b^2-4ac))/2a
a =20, b=28, c= 2
Substitute into the equation
x= (7+√39)/10. = 1.32
x = (7-√39)/10 = 0.076
Answer:
16.2p (If lemonade is .75p, if not substitute in the equation below)
Step-by-step explanation:
In 4 liters, there would be 3 liters of lemonade and 1 liter in juice.
I am assuming 75p is meant to be .75p
So 4 liters costs: (1 x 1.8) + (3 x .75) = 4.05
We need 16 so: 4.05 x 4 = 16.2
