$\dfrac{1}{9} - \dfrac{5}{6}$

Set up

$\dfrac{2}{18} - \dfrac{15}{18}$

Get all fractions to a common denominator which will allow you to subtract them

$\dfrac{2 - 15}{18}$

Subtract numerators

$\boxed{- \dfrac{13}{18}}$

Simplify

6x+2y=12 solve for y,state the m and b,and graph

kramer

Move 6x to the right side: 2y=12-6x
Divide both sides by 2: y=6-3x
m is the slope which in this case is -3
To see a graph plug y=6-3x into the website wolfram alpha!
Hope this helps!!

Factor completely.<br> 150m^2nz+20mn^2c-120m^2nc-25mn^2z

Anika [276]

Answer:

The factor form is:

$5mn\left(6m-n\right)\left(5z-4c\right)$

Step-by-step explanation:

Here we have to find the factor of the expression:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z$

So we need to take out the common terms, as we do for finding the greatest common factors.

Now the expression that is given can be re-written as:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z\\=150mmnz+20mnnc-120mmnc-25mnnz\\=30\cdot \:5nmmz+4\cdot \:5nmnc-24\cdot \:5nmmc-5\cdot \:5nmnz$

Next, we will find the common terms, as follows;

$30\cdot \:5nmmz+4\cdot \:5nmnc-24\cdot \:5nmmc-5\cdot \:5nmnz\\=5nm\left(30mz+4nc-24mc-5nz\right)\\$

Now we will factorise the expression:

$\left(30mz+4nc-24mc-5nz\right)\\$

as follows;

$\left(30mz+4nc-24mc-5nz\right)\\=6m\left(5z-4c\right)+n\left(4c-5z\right)\\=\left(-4c+5z\right)\left(6m-n\right)\\$

So the final factor form is:

$150m^2nz+20mn^2c-120m^2nc-25mn^2z=5mn\left(6m-n\right)\left(5z-4c\right)$

Find the circumference with the given radius.round to the nerest tenth.use 3.14 π r = 7cm

brilliants [131]

Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

$C=2\pi r$

So we can substitute 7 for r and 3.14 for pi:

$C=2(3.14)(7)=43.96$ cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.
