Answer:

15° = x

Step-by-step explanation:

By the Supplementary Angles Theorem, you add m<x by 165, and set that equal to 180°, or π. Of course you have to do the inverse of addition in order to get this, so deduct 165 from 180 to end up with 15.

5/8=n/n-9Solve each equation

QveST [7]

$\begin{gathered} \frac{5}{8}=\frac{n}{n-9}(\text{cross multiplying it)} \\ 5(n-9)=8n \\ 5n-45=8n \\ 5n-8n=45 \\ -3n=45 \\ n=-15 \end{gathered}$

So, the answer to the equation is n=-15

-4x+6(x-1) simplify algebraic expression

vladimir1956 [14]

Hey there

the answer is

−4x+6(x−1)

Distribute:

=−4x+(6)(x)+(6)(−1)

=−4x+6x+−6

Combine Like Terms:

=−4x+6x+−6

=(−4x+6x)+(−6)

=2x+−6

thank you

PLEASE HELP ASAP GIVING BRAINLIEST

Answer:

Part 1) $y=32.5x+11.95$

Par 2) see the explanation

Part 3) $\$401.95$

Step-by-step explanation:

Part 1) Write an equation in slope intercept form to represent this problem

Let

x ----> the number of tickets

y ---> the total cost

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the slope or unit rate

b is the y-intercept (one-time processing fee)

In this problem we have

$b=\$11.95$

ordered pairs (4,141.95) and (7,239.45)

Find the slope

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values in the formula

$m=\frac{239.45-141.95}{7-4}$

$m=\frac{97.5}{3}$

$m=32.5$

substitute the values in the linear equation

$y=32.5x+11.95$

Part 2) What does your slope represent in this problem? What does your y-intercept represent in this problem?

a) The slope of the linear equation represent the unit rate, so the slope represents the cost of one ticket

$m=\$32.5\ per\ ticket$

b) The y-intercept is the value of y when the value of x is equal to zero

In this context, the y-intercept represent the one-time processing fee

$b=\$11.95$

Part 3) Use the equation to find how much Alan would have to pay for 12 tickets

For x=12 tickets

substitute in the linear equation

$y=32.5(12)+11.95$

$y=\$401.95$
