Answer:

3.4 lessons per week

Step-by-step explanation:

If the teacher has to teach 6 chapter in 15 weeks, and each chapter has around 8.5 lessons. it means that the teacher has to teach in 15 weeks a total amount of lessons of 6*8.5= 51.

so 15 weeks---51 lessons

    1 week------x

From the above relation we have= 51/15= 3,4 lessons per week

Daniel puts some wheat flour into an empty bowl. Then he add 2/3 cup rye flour to make a total of 2 5/12 cups of flour. How much
lozanna [386]

Answer:

1 3/4 cups of wheat flour is in the bowl

Step-by-step explanation:

x + 2/3 = 2 5/12

First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12

Then convert the 2 5/12 to an improper fraction 29/12

x + 8/12 = 29/12

subtract 8/12 from both sides

x = 21/12 = 1 9/12 = 1 3/4

Which matrix equation represents the system of equations?<br><br> {-x+ 2y = 0 <br> y= -2
Snowcat [4.5K]

We are given a system of equations,

\begin{cases}-x+2y=0\\y=-2\\ \end{cases}

This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),

\begin{bmatrix}-1&2\\0&1\\ \end{bmatrix}

The matrix will then be applied to the vector (lower dimensions on top),

\begin{bmatrix}x\\y\\ \end{bmatrix}

And the result vector will be whats on the other side of equals sign,

\begin{bmatrix}0\\-2\\ \end{bmatrix}

So to put everything together,

\begin{bmatrix}-1&2\\0&1\\ \end{bmatrix}\begin{bmatrix}x\\y\\ \end{bmatrix}=\begin{bmatrix}0\\-2\\ \end{bmatrix}

Hope this helps :)

Experimental Probability is use to help make predictions by using materials that relate to the that probability so see if it could happen in real life.

When u flip the coin you will have 2 possible choices..heads or tails..so be flipping a real coin you can see your chances ~Amiya
