Answer:

I think the answer is 10 hours

the 11.95 seems wrong

Step-by-step explanation:

\frac{1}{6}   + \frac{1}{y}   = \frac{1}{3.75}

multiply by 22.5 y

3.75 y + 22.5 = 6y

y = 10

A recipe for brownies calls for 4 cups of flour to 6 cups of sugar how many cups of sugar per cup of flour does the recipe requi
Andrews [41]

So, we have 4 cups of flour and 6 cups of sugar and we need to know how many cups of sugar per cup of flour does the recipe require. Because it is requested to know how many cups of sugar per cup of flour does the recipe require, we need to divide the amount of flour and sugar by the amount of flour, and we will know what we need to know.

4 cups of flour / 4 = 1 cup flour

6 cups of sugar / 4 = 6/4 = 3/2 = 1 1/2 cups of sugar per cup of flour is the solution
