Answer:
I help!!
Explanation:
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=?
