When Janice was 20, her brother was 10.

Since the age between them will always be 10 years,

30-10= 20

When Janice is 30, her brother is 20.

I hope this helps!

GalinKa [24]

Answer:

Location.

A point has no physical properties of any sort, so 2 would automatically be out of the question. A point on a number line is represented by a dot, and the location of whatever object you're representing as the dot will be where the dot goes. Therefore, the answer is Location.

Hope this helped!
