Let x be the common factor between chickens and ducks. Then:
6x/(5x-63)=3/1
15x-189=6x
9x=189
x=21
6x=123 chickens were on the farm
☺☺☺☺
You get imaginary roots for this equation.
x=4-5i
x=4+5i
Since you that that line is 180 degrees you can simply do 180-149 and find that the answer is 31 degrees. So you would do 13x+5=31, 31-5=26, 26/13, and then x=2 :)
B.30
cause 60 is 30 halted so yeah
Only Table 2 shows direct variation. Every y value is 7 times the associated x value.
