Q:

Christina and Sarah went on a fishing trip and caught 31 fish. Christina caught one less than three times as many fish as Sarah got. Can you help me set up a 5D table to figure out how many fish each girl caught?

A:
Answer:I think Christina caught 23 fish and Sarah caught 8 fish.Step-by-step explanation:If I did this right, we have to find the equation to represent this situation. Christina caught one less than 3 times as many as Sarah caught. Since we do not know how many Sarah has, we have to use a variable so let's go with x. One less than 3 times as many would be 3x - 1 because one less means subtracting 1 and 3 times means multiply by three. So we have x for Sarah and 3x - 1 for Christina. We add those together to get x + 3x - 1 = 31 (since they caught 31 fish, the total would be 31). We simplify it down to 4x - 1 = 31. Add one to both sides to cancel it out and we get 4x = 32. Divide by 4 on both sides and we get x = 8. Since Sarah was x, Sarah caught 8 fish. To find Christina we just plug in the 8. 3(8) -1. 3 times 8 is 24 and 24 minus 1 is 23. To check our answers we add 8 and 23 together which comes out to be 31. Please correct me if I'm wrong! (Now I'm not sure what you mean by a 5D table but if this is right I hope it helps)
