★ Inequalities ★ 

or n ∈ ( 10 , 11 ) 
Possible value can be easily obtained by generating an arithmetic mean 

Else we've infinite numbers between them , 
According to density property of real numbers , we can have any real number satisfying the given inequality under condition 10 < n < 11 
Which is true for infinite possible numbers 
10.1 , 10.2 , ... INFINITY 
 
        
        
        
Answer:
This shows that the mean increases by 2.95
Step-by-step explanation:
Assume the given data is 2, 5, 6, 8
Mean = 2 +5+6+8/4
Mean = 21/4
Mean = 5.25
If number 20 is added, the data becomes 2, 5, 6, 8, 20
New mean = 2 +5+6+8+20/4
New mean = 41/5
New mean = 8.2
Taking the difference in the mean:
Difference = 8.2 - 5.25
Difference = 2.95
This shows that the mean increases by 2.95
<em>NB: The data used was assumed since we are not given any data in question</em>

To answer this we will add, but before we add we will change 4/5 in to a decimal. to change ANY fraction into a decimal we have to divide the numerator by the denominator. lets do it:- 
4/5 
4 ÷ 5 = 0.8
Now lets substitute 0.8 for 4/5 and then add.
4/5 + 0.05
0.8 + 0.05 = 0.85
CHECK OUR WORK:-
0.85 - 0.8 = 0.05
We were RIGHT!!
So, the decimal 0.85 is equivalent to 4/5 + 0.05.
Hope I helped ya!! xD 
        
             
        
        
        
Answer:
x=-5
Step-by-step explanation:
Combine like terms: 7x-11=-46
Add 11 to -46: -35
Divide: 7x/-35
ANSWER: x=-5
