In the first three rounds, Xander had the following rolls. Write an addition expression that can be used to find his point total at the end of the three rounds

COULD SOMEONE HELP ME PLEASE!!!!!

Respuesta :

the average number of pins he knocks down per role is about 7 1/3

10 + 9 + 7 = 22

22 divided by 3 = 7 1/3

so his pin total would probably be 44
