Set it up as an equation. "A number" is x.
2x-2=x+64
Move all of the x terms to one side by subtracting x from both sides, then add 2 to both sides to isolate x.
X=66
The number is 66
x < - 
add 
to both sides
- 3x > + 
- 3x > 
( divide both sides by - 3 )
note that when we divide/ multiply by a negative quantity we must reverse the inequality symbol
x < -
The answer is C.Triangle ABC is similar to triangle DBA by the SAS similarity theorem
600000000+2000000+50000+100+20+3
D. No because two points with the same x value have different y values. A function cannot have one x equal different y
