Let x,y,z be those numbers.
x+y+z = 12
Since x,y,z are consecutive: y=x+1, and z = x+2
Let's replace y and z by their new values:
x+x+1+x+2=12
3x+3=12
You subtract 3 from each side to get variables on a side, and numbers on the other:
3x=9
You divide both sides by 3:
x=3
y=x+1 = 3+1 = 4
z=x+2 = 3+2 = 5
So the numbers are 3; 4 and 5.
You can re-check your answers (very important):
3+4+5 = 12
3;4;5 are consecutive numbers.

Step-by-step explanation:
Answer:
C. Both x is a function of y and y is a function of x
Step-by-step explanation:
A <u>function</u> is a relationship which assigns to each input (from the domain) value, a unique output (from the range).
y is a function of x means x is from domain, y is from range
x is a function of y means y is from domain, x is from range
1. Given 
y is a function of x because for each x there is exactly one y corresponding to this x.
2. Rewrite
expressing x in terms of y:

x is a function of y because for each y there is exactly one x corresponding to this x.
