Answer:

Julie weighs 35 lbs, Ted weighs 70 lbs, Mike weighs 105 lbs.

Explanation:

Let the weight of Julie be
x

Given:

Ted weighs twice as much as Julie

Weight of Ted =
2x

Mike weighs three times as much as Julie.

Weight of Mike =
3x

Together, Ted, Mike, and Julie weigh 210 lbs.


x+2x+3x=210

Solving above we get;


6x=210\\x=(210)/(6)=35\ lbs

Hence Julie weight is 35 lbs.

Weight of Ted =
2x=2* 35 = 70 \ lbs

Hence Ted weight is 70 lbs.

Weight of Mike =
3x=3* 35 = 105 \ lbs

Hence Mike weight is 105 lbs.
