Answer:
Transitive property of equality
Step-by-step explanation:
The Transitive property of equality says that:
If a,b and c are three elements such that
a=b and b=c
then, a=c
Here, we are given
a = 0.5b and 0.5b = 10
On comparing it with above property
a=a, b=0.5b and c=10
such that a=b and b=c
then, a=c
i.e. a=10
