Answer:
Step-by-step explanation:
(x,y)→(-x,-y)
Divide.
1/3 / 5
Or multiply by the reciprocal of 5:
1/3 * 1/5 = 1/15
Therefore 1/15 cup of flour is used to make 1 dinner roll.
We can set up a proportion:
5/1/3 = x/5 2/3
Multiply 5 2/3 to both sides:
28 1/3 / 1/3 = x
85 = x
So 85 rolls can be made with 5 2/3 cups of flour.
x = the number of hours
write an equation of the problem: 8x + 20 = 52
subtract 20 from each side: 8x = 32
divide each side by 8: x = 4
