Solve for x.
12x − 6 = − ( 18x + 11 )
A. 6
B. -6
C. 1/6
D. -1/6

Answer:

A.) 53°

Step-by-step explanation:

SPR + RPQ =90°

37° + RPQ = 90°

37° - 37° + RPQ = 90° - 37°

RPQ = 53°

50 magazines

because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50

There are 64 magazines in the library.

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.

We have to given that;

The ratio of books to magazines in the children's section at the library is 5: 2.

Let number of books = 5x

And, Number of magazines = 2x

Here, There are 225 books in the library.

Hence, We can formulate;

⇒ 5x + 2x = 225

⇒ 7x = 225

⇒ x = 32

Hence, Number of magazines = 2x

                                               = 2 × 32

                                               = 64

Step-by-step explanation:

Pertains to y-intercept is then 0.

It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Answer:

[tex]=-1\frac{5}{9}[/tex]

Step-by-step explanation:

We want to write:

[tex]-1.\bar{5}[/tex]

As a mixed number in the simplest form.

We can use the following algebraic trick. First, we can ignore the negative and add it on the very end. So, we have the number:

[tex]1.55555...[/tex]

Let's let this equal to n. So:

[tex]1.55555...=n[/tex]

Now, we will multiply n by 10^x for the number of repeating digits x.

There is only one digit repeating (the 5). So, we will multiply both sides by 10^1 or just 10. This yields:

[tex]15.55555...=10n[/tex]

Now, we will subtract n from both sides. This yields:

[tex]15.5555...-n=10n-n[/tex]

On the right, we will just get 9n.

However, let's replace n with 1.5555... on the left. This yields:

[tex]15.5555...-1.5555...=9n[/tex]

All of the repeatings 5s will cancel. 15-1 is 14. So:

[tex]14=9n[/tex]

Now, divide both sides by 9. So, our n is:

[tex]n=\frac{14}{9}[/tex]

And since we originally set n to be 1.5 repeating, this is equivalent to:

[tex]n=1.\bar{5}=\frac{14}{9}[/tex]

And now, we can add back the negative:

[tex]-1.\bar{5}=-\frac{14}{9}[/tex]

We can rewrite this as:

[tex]=-(\frac{9}{9}+\frac{5}{9})[/tex]

So, as a mixed fraction, our decimal is:

[tex]=-1\frac{5}{9}[/tex]

And we're done!
