X+y+z=51
y=2z
z=9+x
subsitute those
x+2z+9+x=51
x+2(9+x)+9+x=51
x+18+2x+9+x=51
4x+27=51
minus 27 both sides
4x=24
divide by 4
x=6
sub back
z=9+x
z=9+6
z=15
y=2z
y=2(15)
y=30
the numbers are
6,30,15
The symbol they are using is that of a ray so, order matters.
Ray BC is telling you the ray starts at point B like a line segment BUT continues on towards and through point C rather than stopping at it.
Ray CB is telling you just the opposite; the ray starts at point C, continues on towards and through point B.

Answer:
Step-by-step explanation:
We have been given the zeroes of polynomial which are -1,2,7
That means the factors are (x+1) (x-2) (x-7)
When we want to a polynomial from zeroes we multiply the factors
Hence, the required polynomial is:
Answer:180
Step-by-step explanation:
72 x 2 = 144
72 ÷ 2 = 36
144 + 36 = 180
