2x + 8y = 21 6x - 4y = 14

Step-by-step explanation:

{2x+8y=14

{216x-4y=14

{x+4y=7

{216x-4y=14

217x=21

x=3/31

2*3/31+8y=14

y=107/62

(x,y)=(3/31, 107/62)

2*3/31+8*107/62=216*3/31-4*107/62=14

14=14=14 since all of the equalities are true the order pair is the solution of the system (x,y)=(3/31, 107/62)

hope this helps :)

answer: 26

step-by-step explanation:

well, michelle wanted to measure the height of her school's flagpole she placed a mirror on the ground 48 feet from the flagpole then walk backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft from the mirror using similar triangles find the height of the flagpole to the nearest tenth of a foot find the geometric mean of them pair of numbers. its easy math

what level of math? also i don't need to be paid if i can you.
