A bag has more green balls than blue balls, and there is at least one blue ball. Let b represent the number of blue balls and let g represent the number of green balls. Let's compare the expressions 2b and b+g. Which statement is correct?
A. 2b>b+g
B. 2b C. 2b=b+g
D. There is not enough information to tell.

Respuesta :

Answer:

I would say D

Step-by-step explanation:

With the given information I can make 2 expressions:

g>b

b≥1

They do not tell us anything about 2b or what the sum of g+b would be equal to

Answer:

Option D can be the answer.

Step-by-step explanation:

A bag has more green balls than blue balls, and there is at least one blue ball. We can say that -

b is greater than or equal to 1  

and g is always greater than b.

With respect too g, we can say b is:

g-1 or g-2, or generally g-n.

The equation thus becomes: 2(g-n) = g-n + g  

which is equal to: 2g - 2n = 2g - n.  

From this equation we can conclude that the left side is always smaller than the right side so:

2g - 2n < 2g - n.

Which becomes: 2b < g + b.

Hence, option D can be the answer.
