Suppose that b and c are points on the number line . if bc = 10 and b lies at 3 , where could c be located?
katrin [286]
C would be located around 3.3

Bc=10 meaning b x c= 10
B lies at 3
(Opposite of time is division as you probably already know) so 10/3 is 3.3

(I’m sorry if this wrong but hope it is not and you understand it)
