Charles and Lisa were having a watermelon eating contest. They ate twelve slices of watermelon between the two of them. Lisa ate
uranmaximum [27]

Answer:

8 slices

Step-by-step explanation:

Let the watermelon eaten by Charles be A and Lisa be B

They ate 12 slices of watermelon between them

That’s

A + B = 12

Also, Lisa ate 2 times as Charles

that’s

B = 2A

We no have two equations

1. A + B = 12

2. B = 2A

Substitute 2A for B into the first equation

A + B = 12

A + 2A = 12

3A = 12

Divide both sides by 3

3A/3 = 12/3

A = 4

Charles ate 4

Recall Lisa B ate twice as Charles A

B = 2A

B = 2 x 4

B = 8

Lisa ate 8 slices of watermelon
