In mathematical form, it would be:
n-8 < 11
add 8 from both sides,
n-8+8 < 11+8
n < 19
So, n value must be less than 19
Hope this helps! 
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The question is not clear. However, I will treat the question as:
 
 

and:


Solving:  and
  and  

Divide both sides by 26


Divide both sides by 50

Solving  and
 and 

Express 1 as 2^0

Remove bracket

Cancel out 2

Divide both sides by 6



Express 1 as 5^0

Cancel out 5^0

 
        
             
        
        
        
Answer: (-5x2 - 8x + 7) - (5x2 - 4)
Step-by-step explanation:
= -5x2 - 8x + 7 - 5x2 + 4
= -5x2 - 5x2 - 8x + 7 + 4
= -10x2 – 8x + 11
Answer: = (-5x2 - 8x + 7) - (5x2 - 4)
 
        
             
        
        
        
The required equation is:

Step-by-step explanation:
Given
Let a be Anne's Age
and
b be Betty's age
Now we will onvert the given word problem in the form of equation step by step
"twice Betty's age." will be represented by 
Then
"3 years younger than twice Betty's age."  will be represented as: 
Now
"Betty's sister, Anne, is 3 years younger than twice Betty's age."

Hence,
The required equation is:
