Let x = liters 20% solution to be added
then
.12(12) + .20x = .14(12+x)
.12(12) + .20x = .14(12+x)
1.44 + .20x = 1.68 + .14x
.20x = .24 + .14x
.06x = .24
x = 4 liters
Hope this helped!!
Answer:
we get rectangular coordinates,
x= 
y = 
Step-by-step explanation:
We have given,
Polar coordinates ,P = (r , θ) = (3 ,
)
We nee to find rectangular coordinates:
Since , x =rcosθ and y = rsinθ
i.e x = 3cos(frac{-pi}{3}[/tex]) = 3×
= 
And y = 3sin(frac{-pi}{3}[/tex]) = 3×
= 
Hence we get rectangular coordinates,
x= 
y = 
Do you have answer choices, or is this an open-ended one?
Answer: y=x-4
Step-by-step explanation: The y value is exactly x minus four.
