You need more information than that to solve for x and y. However, it is possible for you to graph the equation and see what all the possible values for x and y can be. A possible coordinate can be x=3 and y=3.

I'm not sure what you need to solve for, so I'll solve for both x and y.

3x + 6y = 27
3x = 27 - 6y
x = (27 - 6y)/3
x = 9 - 2y
so there's x
3x + 6y = 27
6y = 27 - 3x
y = (27 - 3x)/6
y = 4.5 - .5x
And there's y

2n^3-3n^2+2n=o<br>answer needed urgently pls

Kazeer [188]

$n = 0$

Step-by-step explanation:

<h2><em>Factor the </em><em>expression</em></h2>

<em> $2n ^ 3 - 3n ^ 2 + 2n = 0$ </em>

<h2><em>Separate into possible cases</em></h2>

<em> $n(2n ^ 2 - 3n + 2) = 0$ </em>

<h2><em>Solve the equation</em></h2>

<em> $n = 0[tex]n = 0 \: \: \: \: \: \: \: \: [tex]n = 0 \: \: \: \: \: \: \: \: 2n ^ 2 - 3n + 2 = 0$ </em>

<h2><em>Find the union</em></h2>

<em> $n = 0[tex]n = 0 \: \: \: \: \: \: [tex]n = 0 \: \: \: \: \: \: n = R$ </em>

<h2><em>there </em><em>for </em></h2>

<em> $n = 0$ </em>

Who started the problem correctly? The problem form is (-5) - (-1 3/4).

Veronika [31]

Answer:

Shane started the problem correctly

Step-by-step explanation:

We are given problem (-5) - (-1 3/4).

Mariah started the problem as (-5) + 1 - 3/4

Shane started the problem as (-5) + 1 + 3/4

We need to find who started the problem correctly.

The problem should be started by converting the mixed fraction into improper fraction i,e

$-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})$

Now we will solve bracket by multiplying -1 with term inside the bracket i.e

$=-5+\frac{7}{4}$

$= \frac{-13}{4}$

Let's compare both the procedures now:

Mariah:

$(-5) + 1 - \frac{3}{4}$

$=(-5) - \frac{1}{4}$

$=\frac{-21}{4}$

Therefore, Mariah did not start the problem correctly.

Shane:

$(-5) + 1 + \frac{3}{4}$

$= -5 + \frac{7}{4}$

$= \frac{-13}{4}$

Therefore, Shane started the problem correctly.

Which shows the list of numbers in order from least to greatest?

nirvana33 [79]

Answer:

-1, |-2|, |-3|, |3.5|, |3²|

Step-by-step explanation:

Calculate the absolute value (the absolute value of any number is always positive): 3, 3², 2 , 3.5, -1

Calculate the exponents : 3, 9, 2 , 3.5, -1

Put in order least to greatest : -1, |-2|, |-3|, |3.5|, |3²|
