A baseball player got 71 hits one season. He got h of the hits in one game. What expression represents
Nikitich [7]

Answer:

  71 -h

Step-by-step explanation:

The player had 71 -h hits in the rest of the games.

_____

In case you cannot write down this answer right away, you can figure it this way. Let r represent the hits the player got in the rest of the games. Then the player's total of hits for the season was ...

  r + h = 71

Subtracting h from both sides of this equation tells us what r was:

  r +h -h = 71 -h

  r = 71 -h . . . . . . . hits in the rest of the games

The player had 71 -h hits in the rest of the season.
