If ef - 3x - 11, fg = 4x-10, and eg - 28, find the values of x, ef, and fg. the drawing is not to scale.
x = 1. ef = 10. fg - 18
x - 1. ef = -8.fg = -6
x-7. ef = 10. fg - 18
x - 7. ef = 32.fg - 38

Part 1)

Part 2)

Part 3)

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of x

we know that

---> by addition segment postulate

we have

substitute

solve for x

step 2

Find the value of EF

substitute the value of x

step 3

Find the value of FG

substitute the value of x

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.

step-by-step explanation:

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
