Suppose the Cote family truly enjoys digestive biscuits.
Late one night, Papa Cote ate one-sixth of the family's digestives.
Early the next morning, Mama Cote ate one-fifth of the remaining biscuits.
Shortly thereafter, Brother Cote consumed one-quarter of the delicious snacks left.
At lunchtime, Sister Cote devoured one-third of the remaining tasty treats.
Finally, Baby Cote ate one-half of the remaining digestive biscuits.

How many delightful digestive biscuits were at first?

I can't quite figure out how to solve this... I would imagine that there should be an end amount or some value from in between... I just don't know. Please help?

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

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.
