Hey there Wcrystasia!!!!! The first thing that you need to realize is what slope-intercept form is. Remember that it is y=mx+b. I always say one variable on the left, while everything else is on the right. After you do that, you need to set up some equations. Seats Each cycle has 1 seat. You know there are 21 seats. So

<span>u+b=21

</span>Manipulate that equation into something that looks like slope-intercept form.

<span>u+b=21

</span><span>u+b−b=21−b

</span><span>u=21−b

</span>Now just rearrange the terms on the right side. You have an answer. If you needed the other equation, it would be set up like

<span><span>u+2b=30

SO the answer is 30 !!!! HOPE I HELPED!!!!!!!!!!!

the local theater is showing a matinee and offering a special deal for the community. A ticket for an adult costs $11 and a tick
Montano1993 [528]
We will call an adult ticket <em>a</em>, and a child ticket <em>c</em>.

Since they sold 60 tickets in total, we can form the equation:
a + c = 60

We can also say that the sum of money from the adult tickets and child tickets combined is 460.
Thus we can say
11a + 6c = 460

Now, we must solve our system.

a + c = 60
11a + 6c = 460

6a + 6c = 360
11a + 6c = 460

-5a = -100
a = 20

Thus, (20) + c = 60
c = 40

a = 20 and c = 40

Can anyone help me ?
taurus [48]

Answer:

_

66,6% = ⅔

_

33,3% = ⅓

85% = 17⁄20

80% = ⅘

75% = ¾

90% = 9⁄10

20% = ⅕

10% = ⅒

Step-by-step explanation:

To convert from a fraction to a percentage, divide both the denominator and numerator to get a decimal point, then move the decimal point twice to the right, then attach the percentage symbol:

⅒ = 0,1 = 10%

⤻⤻

⅕ = 0,2 = 20%

⤻⤻

9⁄10 = 0,9 = 90%

⤻⤻

¾ = 0,75 = 75%

⤻⤻

⅘ = 0,8 = 80%

⤻⤻

17⁄20 = 0,85 = 85%

⤻⤻

_ _

⅓ = 0,3 = 33,3%

⤻⤻

_ _

⅔ = 0,6 = 66,6

All those bars above those digits are what are known as bar notation, indicating that digits repeat.

I am joyous to assist you anytime.

15. A rectangle has a length of 2x - 1 and a width of 3x + 7. Find the perimeter of this rectangle.
andrew11 [14]

Answer:

10x + 12 and 6x² + 11x - 7

Step-by-step explanation:

The perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is length and w is width )

   = 2(2x - 1) + 2(3x + 7) ← distribute parenthesis

    = 4x - 2 + 6x + 14 ← collect like terms

     = 10x + 12

--------------------------------------------------

The area (A) of a rectangle is calculated as

A = lw

   = (2x - 1)(3x + 7) ← expand using FOIL

    = 6x² + 14x - 3x - 7 ← collect like terms

    = 6x² + 11x - 7
