A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 3 cups of ingredient A. How many cups of ingredient B do you need?

8.4cups

Step-by-step explanation:

Given:

recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B.

By using the ratio of both ingredients

Let X= amount of ingredient A in cups

Let Y= amount of ingredient B in cups

We can interpret like this

(X/Y) = (1/2 cup)/(1 2/5 cups)

1 2/5 cups = 7/5 cups

(X/Y) = (1/2)/(7/5)

(7/5)X= (1/2)Y

We can find the value of Y

Y= 2*(7/5)X

Y = (14/5)X

You use 3 cups of ingredient A. Then X= 3cups, then Y=

Y = (14/5)× 3

Y=8.4cups

There are 8.4cups cups of ingredient B do you needed

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
