9
Step-by-step explanation:
X+X+1+X+2=30
3x+3=30
-3. -3
3X=27
Divide by 3
X=9
Infinite! You can, for example, add -1 and 1 to the equation and make it equal. In x=5, you can have x=5+1-1. and it'd still be the same. To add on to it, you could do x+1-1=5+1-1, etc..
I believe its 24 inches because you add up 7+10+7 to get 24.
Answer:
x = 24
Step-by-step explanation:
1.) put the equations together and equal them to 180
2x + 4 + 6x - 16 = 180
2.) combine like terms
8x - 12 = 180
3.) divide both sides by 8
8x = 192
4.) simplify
x = 24
I think it's all real numbers . Not sure
