Answer:

Equation:

6(7.6x+10.4)=737.28

Solution:

x=14.8\ centimeters

Step-by-step explanation:

<u>Perimeter of a hexagon </u>

We are given the length of the side of a regular hexagon

l=7.6x+10.4\ centimeters

And we also know the perimeter of the hexagon is

P=737.28\ centimeters

The perimeter of a regular hexagon is 6 times its side, so

P=6l=6(7.6x+10.4)

The equation that will give the relation to solve for x is

6(7.6x+10.4)=737.28

Reducing

7.6x+10.4=122.88

7.6x=122.88-10.4=112.48

\displaystyle x=\frac{112.48}{7.6}

x=14.8\ centimeters

Can you please help me with 19 20 21 22 and look at the green bar that has all the info thank you
abruzzese [7]
19. 10 divided by 3 = 5 pounds
20. 5.5 divided by .5 = 11
21. no because 1.25 x 2.5 = 3.12 and she only has $3
22. the restaurant because the restaurant wants to buy 30lb and its $1.25 so 30 x 1.25 = 37.5  and the hotel buys 12 lb for $3 so that is 12 x 3= 36

36x – 8y2 when x = 3 and y = –6
sergiy2304 [10]

Welcome to Brainly! :)

I cannot understand your equation, therefore I have put it as 36x + 8y + 2. If I'm wrong let me know and I'll fix everything. :)

We need to plug in our values for what we are given.

Let us learn about plugging in.

Let's start with an example equation:

1x + 3y + 1 - Values: y = 2, x = 4 This is a simple equation.

- When it tells you to plug in or tell you the values, that's your ket to plug in the variable for what it tells you.

Now, let's solve this example, our equation is:

1(4) + 3(2) + 1

Now, we have the original equation but plugged in. Next we simplify:

4 + 6 + 1

Add it up and get 11.

Great! Now that we are done with notes, we can solve.

36x – 8y + 2

It tells us that x = 3 an y = 6. Like the equation, we need to plug it in.

36(3) - 8(-6)+2

Great, now we need to simplify.

36(3)-3(-6)+2 \\ 108 + 18+2\\

Cool, now we simplify and get 128!

Great job!

I hope you had amazing experience with brainly! :D

I need help but I need the correct answer everyone is giving me the wrong answer !!
Jlenok [28]

Answer:

y - 2 = 6 (x - 1)

Step-by-step explanation:

Slope intercept form equations look like this:

y - y1 = m (x - x1)

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

Using the point (1,2), we know that x1 = 1 and y1 = 2. Let's sub these values into the slope intercept equation:

y - 2 = m (x - 1)

To complete this equation, we need to find slope. Pick out another point on the graph and plug into the slope equation. We can use point (2,8), where (1,2) = Point 1 and (2,8) = Point 2.

\frac{y2-y1}{x2-x1}=\frac{8-2}{2-1} =\frac{6}{1} =6

Now that we know m = 6, let's plug that back into the original equation to get our final answer:

<u>y - 2 = 6 (x - 1)  </u>          

I hope this helps!
