Find the quotient please
LenKa [72]

Answer:

-7.

Step-by-step explanation:

Fractions are division! If you don't know what a quotient is, It is basically a more complicated way of saying "find the answer by dividing." So we always divide the numerator (top number) by the denominator (bottom number). So we get 14÷-2 and we can see that -2 is a negative number, so remember that a positive times or divided by a negative is always a negative number. So therefore we get -7 as our quotient.

A professional baseball team won 84 games this season . The team won 14 more games than it lost. Therwe qere no ties how many ga
Natalka [10]

We are given the professional baseball team won = 84 games.

Let us assume the team loss = x games.

According to problem, "the team won 14 more games than it lost".

14 more than x could be given by expression " x+14".

Therefore, we can setup an equation

x+14 = 84.

Subtracting 14 from both sides, we get

x+14-14 = 84 -14

x = 70.

Team loss = 70 games.

Total number of games played = Number of games win + number of games loss.

= 84 +70 = 154 games.

Therefore, total 154 games were played.
