In the final inning of a baseball game, the score is 7 to 5. Which inequality represents the number of runs, that the losing
team must score in order to take the lead?

Or+5<7
Or-5>7
Or-5<7

Answer:

[tex]O_r+5>7[/tex]

Step-by-step explanation:

Let:

[tex]L_t=Losing\hspace{3}Team\hspace{3}Score\\L_w=Winning\hspace{3}Team\hspace{3}Score[/tex]

It is clear that, if the losing team is attempting to win its score must be greater than the score of the winning team. Mathematically, this can be written as:

[tex]L_t>L_w[/tex]

Now, let:

[tex]O_r=Number\hspace{3}of\hspace{3}runs[/tex]

According to the problem:

[tex]L_t=5\\L_w=7[/tex]

So:

[tex]5>7[/tex]

This is not true. However, we need to modify the  inequality in order for it to make sense, in another words add to the losing team score a certain amount of runs:

[tex]5+O_r>7[/tex]

If we solve the inequality:

[tex]O_r>2[/tex]

Which is true, because if the lose team wants to take the lead it need to score more than 2 runs.

Therefore, the inequality which represents the number of runs that the losing  team must score in order to take the lead is:

[tex]O_r+5>7[/tex]

7v7

Answer:

A) r + 5 > 7

Step-by-step explanation:

if "r" is the number of runs they need to win, plus the amount they already have, it would need to be greater than 7.

so basically,

r + 5 = something greater than the other team's score, 7, so they can take the lead.

so it is r + 5 > 7
