Find the equation that best represents the following word problem: In a certain freshman class, the number of girls is 83 less than twice the number of boys (b). The total number of students in that freshman class is 259. How many boys and girls are in that class? A) b + 2b = 259 - 83 B) b + 2b – 83 = 259 C) b + 83 – 2b = 259 D) b + 2b = 259

(B)

Step-by-step explanation:

We can first create the equation , since we know that there are a total of 259 students in this freshman class.

Now, the amount of girls is 83 less than twice the number of boys, so that is .

Now, we can substitute this in the previous equation as g.

Hope this helped!

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.
