Draw a diagram to determine the length of segment AN. Segment GO is 5cm long. O is the midpoint of GN. G is the midpoint of RO. D is the midpoint of DG. A is the midpoint of RG. What is the length of segment AN?

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

4.5%

step-by-step explanation:

the value of x is 28.2
