1/2r=5/2 help please
1/2r(2)=5/2(2) 1r=5 r=5
|dw:1348628696973:dw|
1/2r=5/2 (2/1) 1/2 r= 5/2(2) r = 5
Pretty much, multiply 1/2r by its reciprocal, which is 2, to cancel it out and get x alone. Then, multiply the other side by 2 and that would simplify to r=5, as others before me... already said. :)
