Answer:
Step-by-step explanation:
one whole cake is 5/5
to get 5/5 from 1/5 we multiply by 5
so to find the amount of flour needed, we also multiply by 5
5(1/2)
5/2 cups of flour required for one cake
Answer:
2 21/40
Step-by-step explanation:
First, you take the fractions in the parenthesis and make the denominators alike by finding the least common multiple. Once you've done that you can add them together and then add the outer fraction. When adding the outer fraction, you need to make it into an improper fraction. I hope this helped! :)
Y α 1/x
y = k/x Where k is the constant of proportionality.
xy = k Cross Multiplying.
k = xy
Recall y= -8 when x = -9
k = -9 * -8 = 72
Finding y when x = 4.
k = xy
72 = 4y Divide both sides by 4.
y = 72/4 = 18.
y = 18.
