The Equation C = 2D shows how the cost of a car ride depends on the distance in miles. The Variable D Represents the number of miles driven, and the Variable C represents the cost in dollars. If a Car ride is 10 miles long, how much will it cost?

A)15
B)30
C)20
D)25

$ 20

Step-by-step explanation:

Step 1:

Equation is given by C = 2D

Here D is equal to 10 miles

Variable C costs twice the distance traveled.

Step 2:

Here D= 10 Miles.

Hence, C= 2*10 = 20

Hence $20 will be the cost.

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.
