R is the midpoint of QS, if QR=2x and RS=x+3, what is RS?

lbvjy [14]

Q -------------R------------S

suppose this is your line,

R is the mid point

and it's given that

QR = 2x
and
RS = x+3

as R is the mid point of QS
so,
QR = RS
then,
2x = x + 3
2x - x =3
x = 3

as,
it's given that RS = x + 3
then,
RS = 3 + 3
= 6 units.
