On all sides of a triangle it’s about 7 inches
        
             
        
        
        
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20

Answer with explanation:
Income earned by my parents in every two weeks = $ 1046.78
In two weeks there are 14 days, so income earned by my parents in 1 day
               
Income of my parents after a month, if there are 30 days in a month = $74.77 × 30= $ 2243.10
We, will use , rule here , which states that , 28% of monthly income of my parents, should be used for  monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.
 rule here , which states that , 28% of monthly income of my parents, should be used for  monthly housing expenses ,and 36% of gross monthly income should be used for debt purposes.
28% of $2243.78
 
 
= $ 628.26 (Approx)
So,my parents, monthly housing expense should not exceed ≥ $ 628.26
