Need urgent , will give brainliest. 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.

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.

a and b are equal

step-by-step explanation:

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
