Ineed on 15 & 16.
and pls show the work that’s the part that’s giving me trouble

Step-by-step explanation:

# 16

180 degrees total in a triangle

Largest angle = 8x

Middle angle =3X

Small Angle = 1 X

Total   12 X = 180 degrees

X = 15 degrees

8 times 15 =  120 degrees

3 times 15 =  45 degrees

1 times 15 = 15 degrees

Check   120 + 45+ 15 = 180 degrees

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!

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.
