Answer:
let x be the Robert piece
y Maria's piece
x+y=10
0,5*x ( half of Robert piece)= 2/3 y( 2 thirds)
2 equations then
x+y= 10 then x= 10-y
0,5x= 0,67 y then we replace x by 10-y on the second equation and it gives
0,5(10-y)= 5-0,5y=0,67y
5= 1,17 y so y= 4,27 and then x= 10-y= 5,73
the question asks how much Robert wire is longer than Maria's wire
so we get x-y= 1,46
N/6 = - 8
Multily both side by 6
N = -48
Divide negative 16 by both sides
v=2
