Answer:
x=-1
Step-by-step explanation:
By adding the bottom lines you can get
2x+11 = x+10
Simplifying this gets you 
x=-1
 
        
             
        
        
        
Answer:
x² - 3x + 5 - [24÷(x+3)]
Step-by-step explanation:
1. Expand (x³ + 2x - 6x - 9)
             = x³ - 4x - 9
2. Divide [x³ - 4x - 9 by x+3]
             = x² + [(-3x^2-4x-9) ÷ (x+3)]
3. Divide [(-3x^2-4x-9) by (x+3)]
             = -3x + [(5x-9) ÷ (x+3)]
x² - 3x + [(5x-9) ÷ (x+3)]
4. Divide [(5x-9) ÷ (x+3)]
             = 5 + [(-24) ÷ (x+3)]
x² - 3x + 5 + [(-24) ÷ (x+3)] 
= x² - 3x + 5 - [24 ÷ (x+3)]
 
        
             
        
        
        
When you plot the data in a pie graph, it looks like that shown in the picture. A circle is formed when you draw a point and connect it from end to end forming a complete revolution. One revolution equals 360°. Therefore, each piece of pie for each type of book is a fraction of one revolution. The fraction can be determined by dividing the number for a specific type of book to the total number of books. Specifically, the fraction for the Self Help slice would be 90/375 which is equal to 0.24 or 24%. Then, 24% of 360 is 86.4. Therefore, the central angle formed by the Self Help slice is 86.4°.
 
        
        
        
Answer:
Each family spent about 34.25 on dinner
Step-by-step explanation:
$167 - $30 (tip) = 137
137 ÷  4 (for each family) = 34.25
BUT 
if each family is seperate than they each spent about 11.75 on dinner
167 - (30 x 4) = 47
47 ÷  4 = 11.75 
I'm pretty sure the first one is the answer though
