-1 3/5 divided by -2/3 <br> Write as a mixed number
mihalych1998 [28]

Answer:

2 2/5

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. First convert the first into the improper fraction -8/5. Now because when dividing fractions you keep the first on, change to multiplication and flip the second equation you have

-8/5 x -3/2=?

Now you just multiply across as you would and normal time multiplying fractions. Remember a negative divided by a negative is a positive! And not after you keep, change, flip and multiply you are left with 24/10. Which is equal to 12/5 but you wanted a mixed number so we convert it into 2 2/5

In major league soccer, standings are determined by points. Three points are awarded for each win, 1 point is awarded for each t
Vlada [557]

Answer:

They won 17 games and drew 4 games

Step-by-step explanation:

The given parameters are;

The number of points the major league soccer team finished with = 55 points

The number of games the soccer team played = 28 games

The number of losses the soccer team had = 7 losses

The number of points awarded for each win = 3 points

The number of points awarded for each tie = 1 points

The number of points awarded for each loss = 0 points

Let x represent the number of wins, y represent the number of draws, and let z represent the number losses

Therefore;

z = 7

x + y + z = 28

3·x + y + 7×0 = 55

Therefore, we have the following system of equations;

x + y = 21...(1)

3·x + y = 55...(2)

Which gives;

\begin{bmatrix}1 & 1\\ 3 & 1\end{bmatrix} \begin{bmatrix}x \\ y\end{bmatrix} = \begin{bmatrix}21 \\ 55\end{bmatrix}

The inverse of the matrix is given as follows;

\dfrac{1}{1 - 3}  \times \begin{bmatrix}1 & -3\\ -1 & 1\end{bmatrix} = \begin{bmatrix}-0.5 & 0.5\\ 1.5 & -0.5\end{bmatrix}

Therefore;

\begin{bmatrix}x \\ y\end{bmatrix} = \begin{bmatrix}-0.5 & 0.5\\ 1.5 & -0.5\end{bmatrix}  \times  \begin{bmatrix}21 \\ 55\end{bmatrix}  =  \begin{bmatrix}17 \\ 4\end{bmatrix}

x = 17, y = 4
