Answer:

9 kids tickets

Step-by-step explanation:

Let k = no. of kid's tickets

12 - k = no. of adult's tickets

9.50(12 - k) + 6.50k = 87

95(12 - k + 65k = 870

1140- 95k + 65k = 870

- 30k = -270

k = 9 kids

Help with 27 and 23 plzz
Volgvan
23. I know that there will be 5/12 ribbon left over. You would simply subtract 3/4 by 1/3. I don't know about the first part of this question though. (more like i don't remember)
27. I predict that Susan will get the greater quotient. If you divide the fraction 5/8 by 1/16 you would get 1/2. If you divide 5/8 by 1/32 you would get 1/4. 
1/2 is greater than 1/4, which means that Susan has the greater quotient.

I hope this helps. Sorry about 23. Maybe someone else will answer.

Find the distance between each pair of points. Round to the nearest tenth.
Vsevolod [243]

Answer:

The answer is

<h2>6.7 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

d =  \sqrt{ ({x1 - x2})^{2} +  ({y1 - y2})^{2}  } \\

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M ( 4 , 0) and L ( - 2 , - 3)

The distance between them is

|ML|   =   \sqrt{( {4 + 2})^{2} +(  {0 + 3})^{2}  }  \\  =  \sqrt{ {6}^{2}  +  {3}^{2} }  \\  =  \sqrt{36 + 9}  \:  \:   \\  =  \sqrt{45 }  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 3 \sqrt{5}  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \\  = 6.7082039

We have the final answer as

<h3>6.7 units to the nearest tenth</h3>

Hope this helps you
