Question

Solve this problem on paper using all four steps.

Answer 1

Answer:

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

Step-by-step 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;

$6x=210\\x=\frac{210}{6}=35\ lbs$

Hence Julie weight is 35 lbs.

Weight of Ted = $2x=2\times 35 = 70 \ lbs$

Hence Ted weight is 70 lbs.

Weight of Mike = $3x=3\times 35 = 105 \ lbs$

Hence Mike weight is 105 lbs.
