user100 [1]

Answer:

4x = 44 which is Carolyn's share.

Step-by-step explanation:

x = 11

Answer

4*11 =  44 which is Carolyn's share

2*11 = 22 which is Julia's Share

1*11 = 11  which is Roberta's share.

(5 organisms that live in your house. Identify them and tell me how they interact within the environment and with each other.
lubasha [3.4K]

List five living things in your house (people, animals, plants) and how they interact.

Example: Me, mom, dad, plant, dog. Me and my mom talk and I help her. Same with me and my dad. They both help me. All three of us water and take care of the plant. We play with the dog, feed him, and walk him. The dog sometimes plays with the leaves on the plant.

(I hope this gives you an idea)
