John weighs three times as much as karen. two times john’s weight plus karen’s weight is 875 pounds. how much does john weigh? how much does karen weigh?

Karen's weight = 125 pounds

Step-by-step explanation:

Let Karen's weight be x , this means that John's weight is 3x.

Two times John’s weight = 2(3x)

Two times John’s weight plus Karen’s weight is 875 pounds implies;

2(3x) + x = 875

6x + x = 875

7x = 875

divide through by 7

x = 125

Therefore Karen's weight = 125 pounds

John's weight = 3 x 125 = 375 pounds

1/4 because there is 4 grades.
