Martha's hair was 7 centimeters long after her last haircut, and it grows 10 centimeters
every year. How many years will it take until Martha's hair is 27 centimeters long?

Respuesta :

Answer:2 years

Step-by-step explanation:

7+10+x=27

7 is how long her hair is and it grows 10cm every year, so

27-10=17

17-10=7

You subtracted 10 twice so it's 2 years:)
