1/3 cup of flour is used in 5 dinner rolls. how many cups of flour are needed to make 3 dozen rolls?

3 dozen=3·12=36

Use cross multiplication

1/3·36=5x

12=5x

12/5=5x/5

x=12/5 or 2 2/5 or 2.4

12/5 or 2 2/5 cups of flour is needed to make 3 dozen rolls

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
