R + b = 146.  Supposing that b=r+28, 

r + (r+28) = 146, or 2r + 28 = 146.

Simplifying:  2r = 118.  Then r = 59, and b = r+28 = 59+28 = 87 blue marbles

lubasha [3.4K]

Answer:

No.  I don't have enough Flour to make 5 loaves of bread.

From the Amount of flour i had i can make 4 loaves only.

Step-by-step explanation:

Given:

Flour required for making loaves of bread = 2b cups

Amount of flour i had = 8 cups

Number of loaves of bread = b

We need to find the we have enough flour to make 5 loafs of bread.

Solution:

We know that;

Amount of flour I had is equal to Flour required for making loaves of bread

2b=8

Dividing both side by 2 we get;

\frac{2b}{2} =\frac{8}{2}

b=4
