For this case we have the following expression.

15x + 35y - 40 z

We must find a term of expression that is repeated in all terms.

We then have the number 5.

By doing common factor 5 in all the expression we have:

15x + 35y - 40 z = 5 (3x + 7y - 8z)

Answer:

The factored expression is given by:

5 (3x + 7y - 8z)

The Cubs have won
Naily [24]

First you need to figure out the games the Cubs lost. 11-7=4, so they lost 4 games.

Now you must plug in the ratio of games lost to games played. You know they lost 4 games and played 11, so the ratio would be 4:11.

I hope you find this helpful :)
