tiny-mole [99]

Answer: The team won 100 games and losses 28 games

Step-by-step explanation:

Let the number of games won denoted by x and the games lost is denoted by y .

Given : A minor league baseball team plays 128 games in a season.

Team won 16 more than three times as many games as they lost.

Then, the system of equations, we have

x+y=128-------(1)\\\\x=3y+16------------(2)

We can rewrite equation (2) as x-3y=16----------------(3)

Now, Eliminate equation (3) from (1), we get

y-(-3y)=128-16\\\\\Rightarrow\ 4y=112\\\\\Rightarrow\ y=\dfrac{112}{4}=28

Substitute the value of y in (2), we get

x=3(28)+16=84+16=100

Hence, the team won 100 games and losses 28 games.

It took 3 days to complete a work by 10 people.

         

<h3>What is Efficiency?</h3>

The efficiency is the output of the work which we divide by the work input and then express it in a percentage form.

Here, Efficiency of 1 person to complete a piece of work in 30 days is 1/30.

The number of days to complete the work = n days

Number of person to complete the work = p.

Now, according to question

Number of days to complete the work by 10 people = 30 / 10

                                                                                      = 3 days.

Thus, it took 3 days to complete a work by 10 people.
