Answer:

-16.02

Step-by-step explanation:

I assume the "......" is a variable replacement. I will use x instead.

0.18 = x - - 18 + - 1.8

Negative + Negative = Positive

0.18 = x + 18 + - 1.8

Positive + Negative = Negative

0.18 = x + 18 - 1.8

Combine like terms

0.18 = x + 16.2

Subtract both sides by 16.2 to isolate the variable x

0.18 - 16.2 = x + 16.2 - 16.2

-16.02 = x + 0

-16.02 = x

Check your work:

Plug in -16.02 into the original equation

0.18 = -16.02 + 18 - 1.8

They should equal each other; let's check to make sure

0.18 = 1.98 - 1.8

0.18 = 0.18

They equal each other so our answer is correct

Simplify the rational expression. state any restrictions on the variable. n^4-11n^2+30/n^4-7n^2+10

Andrej [43]

<span>For this case we have the following expression:
</span> $\frac{n ^ 4-11n ^ 2 + 30}{ n ^ 4-7n ^ 2 + 10} 

$
<span> We are going to make the following change of variables:
</span> $x = n ^ 2
$
<span>Rewriting the expression we have:
</span> $\frac{(x ^ 2-11x + 30)}{(x ^ 2-7x + 10)} 

$
<span>Factoring the expression we have:
</span> $\frac{(x-5) (x-6)}{(x-5) (x-6)} 
$
<span>Canceling similar terms we have:
</span> $\frac{x-6}{x-2} 
$
<span>Returning the change we have:
</span> $\frac{n ^ 2-6}{n ^ 2-2} 

$
<span> The resctrictions of the function are those that make the denominator equal to zero.
We have then:
</span> $n ^ 2-2 = 0

n = +/- \sqrt{2} 
$
<span> Answer:
The simplified expression is:
</span> $\frac{n ^ 2-6}{n ^ 2-2}$
<span>The restrictions are:
</span> $n = \sqrt{2} 
$
$n = - \sqrt{2}$

Brooke has to set up 70chairs in equal rows for the class talent show.But,there is not room for more than 20 rows. What are the

Zinaida [17]

Answer:

R = rows

C = columns

The chairs will be arranged in a way such that R * C $\geq$ 70

We know that R $\leq$ 20

70 / 20 = 3.5; however, you can't have half of a chair.

So find all the factors of 70 which don't exceed 20.

1, 70

2, 35

<h2>5, 14</h2><h2>7, 10</h2><h2></h2><h2>There are four ways that Brooke can set up the chairs:</h2><h2>5 rows of 14</h2><h2>7 rows of 10</h2><h2>10 rows of 7</h2><h2>14 rows of 5</h2>
