Answer:[tex]90\ hits[/tex]
Step-by-step explanation:
Let be "r" the total number of runs they scored during the game and "h" the total number of hits they had during the game.
You know that they play a total of 9 innings and they scored 4 runs in every inning.
This means that you can find the total number of runs they scored in 9 innings by multiplying 4 runs by 9. Then:
[tex]r=(4)(9)\\\\r=36[/tex]
Knowing that they scored a total of 36 runs, and knowing that for every 2 runs they had 5 hits, you get that the total number of hits they had during the game is:
[tex]h=\frac{(36)(5)}{(2)}\\\\h=90[/tex]
