Answer:

The answer is " $\frac{26}{7}$ "

Step-by-step explanation:

The whole question can be found in the file attached.

$\to x + \frac{5}{7} = \frac{31}{7}\\\\$

Subtracting the $\frac{5}{7}$ from both sides of the equations:

$\to x +\frac{5}{7} - \frac{5}{7} = \frac{31}{7} - \frac{5}{7} \\\\$

$= \frac{31-5}{7} \\\\= \frac{26}{7} \\\\$

It's just dividing out the factoring to their simplest form.
The bold numbers are the answers that go in the circles.

1. 16 < 8 and 2
8 < 2 and 4
4 < 2 and 2

2. 42 < 14 and 3
14 < 7 and 2

3. 40 < 2 and 20
20 < 10 and 2
10 < 2 and 5

4. I'm not able to see the rest of the factoring tree

Please help fast! give me the equation

uranmaximum [27]

$\begin{bmatrix}x=\frac{\pi }{2}+2\pi n\\ x=\frac{3\pi }{2}+2\pi n\\ x=\frac{3\pi }{4}+\pi n\\ x=\frac{7\pi }{4}+\pi n\end{bmatrix}$

$\begin{bmatrix}\frac{3\pi }{2}+2\pi n=\frac{\pi }{2}+2\pi n\\ \frac{3\pi }{2}+2\pi n=\frac{3\pi }{4}+\pi n\\ \frac{3\pi }{2}+2\pi n=\frac{7\pi }{4}+\pi n\end{bmatrix}$

$\pi =0$

- hope this helps! -
