Answer:
30
Step-by-step explanation:
Ratios always remain proportionate. In this case, the simplified ratio has 1 red car. The question tells us that there are 6 cars. 6 is 6 times bigger than 1; thus showing that the ratio has increased by a factor of 6. If one side of the ratio increases by a factor of 6, then the other side must also increase by a factor of 6. Since 5*6=30, there must be 30 employees that own a black car.
Answer:
y = 1/2x – 9/2 or y = 0.5x – 4.5

Answer:
5/13
Step-by-step explanation:
Answer:
A = 80g B = 200g
Step-by-step explanation for A:
First, you would find what the serving size is divided by to get the number of people needed to feed 6/3 = 2. Then take that number (3) and divided it by the fish (240g) to get 240/3 = 80.
Step-by-step explanation for B:
You will first need to find how much butter goes into ONE pie by dividing 80 by 6 which is 1.33333333333333. Then do 1.333333333333333 times the number of people to feed (15) to get 200.
Your end result has to come out with the unit "gallons."
Write and solve an equation of ratios, as follows:
180 miles 420 mi
-------------- = ------------
12 gal x
Then 180x = 5040, or x = 20
The car would need 20 gallons of gas to travel 420 miles.
