there are 18 pieces of dark chocolate and the ratio of dark and white is 3:2 so we can divide 18 by 3.
18/3 = 6.
This means the ratio of dark chocolate to white as a 1:1 ratio would be 6:6 so we can multiply 6 by 2 to give us the total amount of pieces of white chocolate.
6*2 = 12.
Therefore there are 12 white chocolate pieces.
The answer to your question would be B.
I hope this helped:D
Answer: 60 miles
Step-by-step explanation:
Given
It takes ferry 2 hours to travel to town A and only 
to travel back to town B.
Speed of current is 
Suppose the speed of the ferry is 
mph
Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.
Distance between the towns is 
Isolate the x and the 2 from the top of the equation, then cancel those out from the bottom, then divide out the -1. after that you are left with -6x²+2x-4
Answer:
False
Step-by-step explanation:
We first write the equation in the form ax² + bx + c=0 which gives us:
3x² - 6x + 9=0
Given the quadratic formula,
x= [-b ±√(b²- 4ac)]/2a ,the discriminant proves whether the equation has real roots or not.
The discriminant, which is the value under the root sign, may either be positive, negative or zero.
Positive discriminant- the equation has two real roots
Negative discriminant- the equation has no real roots
Zero discriminant - The equation has two repeated roots.
In the provided equation, b²-4ac results into:
(-6)²- (4×3×9)
=36-108
= -72
The result is negative therefore the equation has no real solutions.
