Is there a picture I can see
        
             
        
        
        
1) 3/5 
2) -10
3) -5/3
4) -3/2
5) -5
6) 4/5
7) 3/5
8) 1/2
9) -1/2
10) -3/7
        
             
        
        
        
(-2)^4 = (-2) (-2) (-2) (-2)  = 16
so n = 16
        
                    
             
        
        
        
Answer:
Option 1 - Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation.          
Step-by-step explanation:
Given : Process 
Step 1: 4x + 2 = 10
Step 2: 4x = 8
To find : Which justification describes the process?
Solution : 
From step 1 to step 2, we subtract 2 both sides
Step 1: 4x + 2 = 10
Subtracting 2 both side,
⇒ 4x + 2-2 = 10-2
Step 2: 4x = 8
So, The best justification is 'Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation'.
Therefore, Option 1 is correct.
 
        
                    
             
        
        
        
Answer:
we conclude that Kiera got the right 63 questions.
Step-by-step explanation:
Total questions = 90
The percentage of correct question = 70%
Using the formula
The number of correct questions = 70% of 90
                                                          = [70/100] × 90
                                                           = 0.7 × 90
                                                            = 63
Therefore, we conclude that Kiera got the right 63 questions.
