Answer:
The one that will not be equivalent to .12 would be A.
Step-by-step explanation:
.12 is not the same as 1.2 for the reason that <em>A is representing a whole number</em> meanwhile <em>.12 is representing a negative number. </em>
Answer: I think A
Step-by-step explanation:
Answer is x+9=11
6+x=9
x=3
15=x+12
x=3
7+x=10
x=3
x+9=11
x=2
So x+9=11 has a different x value than the rest of the equations. So it doesn't belong with the other three.
