Kathleen lost a tooth today. now she has lost 4 more than her sister cara lost.
1. write an expression to represent the number of teeth cara has lost. let k represent the number of teeth kathleen lost.
2. write an expression to represent the number of teeth kathleen has lost. let c represent the number of teeth cara lost.
3. if cara lost 3 teeth, how many teeth has kathleen lost?

I’ll help you out!

1. we know that Cara lost 4 less teeth than Kathleen, and the number of teeth Kathleen lost is represented by K. So, any equation that shows K-4=C will do.(feel free to use that equation)

2. this is essentially the same as the first equation, just reversed. So use + instead of -, and instead of ending up with =C you should end up with =K

You are still using the same plugs, C, 4 and K.

3. This is basic math. Cara lost 3 teeth, Kathleen lost 4 more than cara. So, 3+4=?

452,489 to the nearest thousand is 452,000

x=6 and x=3
