7×20 and 7×2000 are similar. The amount of zeros are the dependent factor.
7×20= 140
7×2000= 14000
The base equation is 7×2=14
Any additions of zeroes in this formula will be added at the end result.
Ex.
7×2=14
7×20=140
7×200=1400
70×200=14000
700×200=140000
        
             
        
        
        
Answer:
-45n-2
Step-by-step explanation:
Let's get rid of parenthesis first using distributive property!
-10n-12+10-35n
Combine like terms!
-10n-35n--12+10
-45n-2 would be the final expression
 
        
                    
             
        
        
        
Answer:
18, the answer to 8+10 is 18, like you learn in 1st grade
 
        
                    
             
        
        
        
V = l * w * h
470.40 = 6.4 * 9.8 * h
Multiply the length and width on the right side of the equation.
470.40 = 62.72 * h
Divide both sides by 62.72
7.5 cm = h
CHECK
V = l * w * h
V = 6.4 * 9.8 * 7.5
V = 470.4 cm^3
        
                    
             
        
        
        
-23 over 5 ÷ 11 over 5 
 -23 × 5 over 5 × 5 
 -115 over 55 
Therefore, your answer would be: -2 and 1 over 11
