bess weigh 20 pounds less than heer brother Brandon. together they weigh 120 pounds. what does each weigh?
Answers
If together they weigh 120 pounds, then each will weigh 50 pounds and 30 pounds.
Step-by-step explanation:
Let Brandon’s weight be “x” pounds.
It is given Bess weighs 20 pounds less than Brandon, so,
Bess’s weight will be = x – 20
Also given that they together weigh 120 pounds.
Therefore, we can now write the equation as,
x + (x-20) = 120
⇒ 2x – 20 = 120
⇒ 2x = 100
⇒ x = 100/2
⇒ x = 50 pounds
∴ x - 20 = 50 – 20 = 30 pounds
Thus, Bess will weigh 30 pounds and Brandon will weigh 50 pounds.
