Answer:
Julie weighs 35 pounds, Ted weighs 70 pounds and Mike weighs 105 pounds.
Step-by-step explanation:
Ted weighs = t
Mike weighs = m
Julie weighs = j
First statement is given " Ted weighs twice as much as Julie." t = 2j
Second statement "Mike weighs three times as much as Julie." m = 3j
Third statement Together weight 210 lbs.
= t + m + j = 210 lbs
= 2j + 3j + j = 210
= 6j = 210
j = 35 lbs
t = 35 × 2 = 70 lbs
m = 35 × 3 = 105 lbs
Julie weighs 35 pounds, Ted weighs 70 pounds and Mike weighs 105 pounds.
Answer:
Weight of Julie=35 lbs
Weight of Ted=[tex]70lbs[/tex]
Weight of Mike=[tex]105 lbs[/tex]
Step-by-step explanation:
Let weight of Julie=x
Weight of Ted=2x
Weight of Mike=3x
Sum of weight of three person=210 lbs
Substitute the values then we get
[tex]x+2x+3x=210[/tex]
Combine like terms
[tex]6x=210[/tex]
[tex]x=\frac{210}{6}[/tex]
Division property of equality
[tex]x=35[/tex]
Weight of Julie=35 lbs
Weight of Ted=[tex]2\times 35=70lbs[/tex]
Weight of Mike=[tex]3\times 35=105 lbs[/tex]
