A new coach was appointed in the middle of a season for a football team. After he took over, the team won 80% of the 60 matches it played. But the overall success rate was only 60%. Find the minimum number of matches the team must have played that season before the new coach took over.

The minimum is 5 matches.

Step-by-step explanation:

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
