Brandon's car gets about 18 kilometers per
liter of gas. She is planning a 3,500 kilometer
trip. To the nearest liter, how many liters of gas
should Brandon plan to buy? At an average
price of $1.15 per liter, how much should
Brandon expect to spend for gas?

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

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.
