1. 1. Erica has 11 cards and Katie has twice as many How many cards do they have all together. We then need to find out how many katie has. 11 x 2=22 - Katie
Katie has 22 cards because if Erica has 11 then you times that by 2 because she has twice as many.
So 22 + 11=33 or 11x3=33 or 33/3=11

2. Erica has 11 baseball cards in her collection. That’s only half as many as Katie has in her collection. How many baseball cards do they have together?

E:11
11 x 2 = 22
K:22
11 + 22 = 33

11 x 2 = 22
22 + 11 = 33

3. To solve this problem I did 11 × 2 =22 and then 11 +22 = 33 so that's my answer

4. E:11 and Katie has double so all you do is 11+11+11=33

From Tai and Cyrus

5. Erica had half the amount of baseball cards so Erica had (11)
Katie had double amount of baseball cards which means she has (22)

22+11=33

6. Erika has 11 and Katie has twice as much so 11 x 2 = 22 which is how much katie has and then you add 11 + 22 = 33

7. Erica has 11 baseball cards in her collection. That’s only half as many as Katie has in her collection. How many baseball cards do they have together?

E:11
11 x 2 = 22
K:22
11 + 22 = 33

11 x 2 = 22
22 + 11 = 33

8. 31 because half of 22 = 11 22 + 11 + 31 (:
