Ted weighs twice as much a Julie. Mike weighs 3 x as muchas Julie.Together they weigh 210lbs. what do ea. weig

Question

Just need to find the weight of each person as a total they weigh 210lbs

Answer 1

2x+3x=210  

5x=210

x=210/5

x=42

ted weighs 84 (2x) and Mike weighs 126 (3x)

Julie represents the unknown which is always labeled (X) you can figure any of these out by solving for "x" as above.

Answer 2

x+2x+3x=210

6x=210

x=35

Julie 35

Mike 105

Ted 70

Answer 3

Julie - 35

Ted - 70

Mike - 105

Answer 4

Your statement of the problem is ambiguous. Assuming that the 210 lbs is the combined weight of Ted, Mike, AND JULIE, then

j + 2j + 3j = 6j = 210

j = 210 / 6 = 35

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

If the "Together they weigh 210 lbs" was only supposed to be the combined weight of Ted and Mike (not the usual approach, but a possible reading as you phrased the problem), then

2j + 3j = 5j = 210

j = 210 / 5 = 42

So in this case, Julie weighs 42 lbs, Ted 84 lbs, and Mike 126 lbs.

I notice others have offered both answers already!

Answer 5

Let x = Julie's weight. Ted weighs 2x and Mike weighs 3x. Together, they weigh 6x = 210lbs. Therefore, x=35 lbs.

Julie weighs 35 lbs, Ted weighs 2×35=70 lbs, amd Mike weighs 35×3=105 lbs.
