You take $22,000.00 + $625.00= 22,625.00 (which is the sales tax)
Take $22,625.00 x .06=$1,357.50
Then take $22,625.00 + $<span>1,357.50 +$40.00 = $24.022.50</span>
        
                    
             
        
        
        
 3:8 is equivalent to 12:32 multiplying by 3 to 12 is 4, so you multiply each number to 4. 3 x 4 = 12 8 x 4 = 32 yes 3:8 is equal to 12:32.
        
                    
             
        
        
        
Distance÷time
440÷8= 55
Therefore he needs to drive at the speed of 55 miles/hour
        
             
        
        
        
Answer:
The expressions which equivalent to   are:
 are:
  ⇒ B
  ⇒ B
  ⇒ C
 ⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
Now let us find the equivalent expressions of  
A.
∵ 4 = 2 × 2
∴ 4 =  
∴   =
 =   
 
- By using the second rule above multiply 2 and (n + 2)
∵ 2(n + 2) = 2n + 4
∴   =
 =   
  
B.
∵ 4 = 2 × 2
∴ 4 =  2²
∴   = 2² ×
 = 2² ×   
 
- By using the first rule rule add the exponents of 2
∵ 2 + n + 1 = n + 3
∴    =
 =   
 
 
C.
∵ 8 = 2 × 2 × 2
∴ 8 =  2³
∴   = 2³ ×
 = 2³ ×   
 
- By using the first rule rule add the exponents of 2
∵ 3 + n = n + 3
∴   =
 =   
 
D.
∵ 16 = 2 × 2 × 2 × 2
∴ 16 = 
∴   =
 =  ×
  ×   
 
- By using the first rule rule add the exponents of 2
∵ 4 + n = n + 4
∴   =
 =   
 
E.

 is in its simplest form
The expressions which equivalent to   are:
 are:

  ⇒ C
 ⇒ C
 
        
             
        
        
        
In system A, the first equation multiply by 4
8x - 4y = 12 (1st)
3x + 4y = 10 (2nd)
--------------------add
11x = 22
So answer is B.
