(n/6 + 8) - 3 = 7
(n/6 + 8) - 3 + 3 = 7 + 3
n/6 + 8 - 8 = 10 - 8
n/6 = 2
(n/6)(6) = 2(6)
n = 12

Answer:
Step-by-step explanation:
1/6 * 42 = 7
"of" means multiply
"is" means =
 
        
             
        
        
        
5x-1 is greater than or equal to -11
        
                    
             
        
        
        
7√7
using the ' rule of radicals '
• √a × √b ⇔ √ab
simplifying the radicals
√28 = √(4 × 7 ) = √4 × √7 = 2√7
√63 = √(9 × 7) =√9 × √7 = 3√7
√112 = √(16 × 7 ) = √16 × √7 = 4√7
substituting into the expression
3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7
