Answer:john weighs 375 pounds.

Karen weighs 125 pounds

Step-by-step explanation:

Let x represent the weight of John.

Let y represent the weight of Karen.

John weighs three times as much as Karen. This means that

x = 3y

Two times John's weight plus Karen's weight is 875 pounds. This means that

2x + y = 875 - - - - - - - -1

Substituting x = 3y into equation 1, it becomes

2 × 3y + y = 875

6y + y = 875

7y = 875

y = 875/7 = 125

Substituting y = 125 into x = 3y. It becomes

x = 3 × 125 = 375

Answer:

John- 375

Karen- 125

Step-by-step explanation:

Answer 1...

j =3k

2j + k = 875

substituting the first eqn into the 2nd

2(3k) + k = 875

6k+ k =875

7k = 875

k =875/7 =125

thus j = 3(125) =375

Solve x3 = 1 over 8. <br> 1 over 2 <br> ±1 over 2 <br> 1 over 4 <br> ±1 over 4
cricket20 [7]
X³ =  1/8

Take the cube root of both sides.

∛x³  = ∛(1/8)

Since x³ has 3 of such x multiplying each other so we bring out 1 of the x from the cube root sign as discussed.

x = ∛((1/2)*(1/2)*(1/2))

We bring out 1 of the (1/2) out of the cube root sign as well.

x = 1/2

So the answer is the first option.  1 over 2.

I hope this helps.
