Geometry math question no Guessing and Please show work thank you

Dahasolnce [82]

we can use

each interior angle formula of any regular polygons

$\theta=\frac{180(n-2)}{n}$

where

n is number of sides

theta is angle

we are given

$\theta=157.5$

now, we can plug it

$157.5=\frac{180(n-2)}{n}$

now, we can solve for n

$1575n=1800\left(n-2\right)$

$n=16$

so, option-C......Answer

8 x 5/6 = z<br> What is z?<br><br> A. 53/6<br> B. 40/6<br> C. 13/48<br> D. 5/48

Answer:

$\huge \boxed{ \boxed{\mathbb{B)} \frac{40}{6} }}$

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

equation
PEMDAS

<h3>given:</h3>

8×⅚=z

<h3>let's solve:</h3>

$\sf multiply \: both \: sides \: by \: 6 : \\ (8 \times \frac{5}{6} ) \times 6 = z \times 6$
$\sf simplify : \\ 8 \times 5 = 6z \\ 40=6z$
$\sf divide \: both \: sides \: by \: 6 : \\ \frac{6z}{6} = \frac{40}{6} \\ z = \frac{40}{6}$

Anyone know the correct answer to this?

Svetllana [295]

Answer:

It should be y=4x-7

Step-by-step explanation:

M is the slope meaning Δx over Δy or rise over run

So if you look at (2,2) and count up to (3,6) the rise is 4 and the run is 1 meaning the slope is 4.

B is the y- intercept so then it would just be -7.
