Answer:
-4x-2 = -2/3
-4x = -2/3 + 2
-4x=4/3
therefore x = (4/3) divide by -4
x = ( 4/3) / -4
x = 4/3 x -1/4
x = -1/3

Answer:
A. Stone bridges to steel bridges=
12 : 20
6 : 10
3 : 5
answer = 3 : 5
B. Steel bridges to Stone bridges
20 : 12
10 : 6
5 : 3
answer = 5 : 3
Total bridges = 20+12=32
C. Total bridges to steel bridges
32 : 20
16 : 10
8 : 5
answer = 8 : 5

The adjacent side of N is 36, and the hypotenuse is 39.
Therefore:
cos(N) = 36 / 39
