The answer to this question is 23. To solve this, write an equation to solve x, This equation will be 12x + 6 = 78. Subtract 6 from both sides to get 12x = 72. Next, divide both sides by 12 to get x = 6. Now, just plug in x for both angles. 4 times 6 is 24, minus 1 is 23. To check this, make sure the other angle (angle NRP) equals 55. 8 times 6 equals 48, plus 7 equals 55. I hope this helped! Could I possibly get brainliest?

I am so stuck! :( Pls help me!!! I don't get the problem and I don't know how to solve it

Answer:

$\frac{n^{2}}{2a}$

Step-by-step explanation:

Just split it up first $\frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}$
Then 9 divided by 18 can be simplified into the fraction 1/2
What can go into $a$ and $a^2$ ? a itself right, so if you divide a by a you get 1, if you divide $a^2$ by a you get a
Same as the a fraction, if you divide $n^3$ by n you get $n^2$
$\frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}=\frac{1}{2}\times \frac{1}{a} \times\frac{n^2}{1}=\frac{n^{2}}{2a}$

What is the solution to this equation:<br> X+7=-8

Brilliant_brown [7]

Answer:

$\boxed {x = -15}$

Step-by-step explanation:

Solve for the value of $x$ :

$x + 7 = -8$

-Subtract both sides by $7$ :

$x + 7 - 7 = -8 - 7$

$\boxed {x = -15}$

So, the value of $x$ is $-15$ .

There are two spinners. Each spinner has 10 equal sectors labeled with the numbers 1 through 10.

Answer:

There are 4 prime numbers from 1 to 10: 2, 3, 5, and 7. This means that there are 4 ways to choose the first outcome. There are 5 composite numbers from 1 to 10: 4, 6, 8, 9, and 10 (1 is just 1). So, you just multiply the two numbers together because each depends on each: 4 * 5 = 20 outcomes.
