Answer:
2
Step-by-step explanation:
$20,000
25,000,000 x 0.0002 = 5,000
5,000 x $4.00= $20,000
Answer:
B
Step-by-step explanation:
A is correct because 
was added on both sides, which is supported by the Additive Property of Equality
C is correct because the Quotient Property of Logarithms states that 
so 
is correct
D is correct because using the fact that 
it is easy to figure out that x=12
For B, there is no property supporting that statement.
To answer this item, we let x be the first positive integer. Then, the second would be x+1. Their reciprocals would be 1/x and 1/(x+1). Then, the equation that would best represent the scenario above is,
1/x + 1/(x+1) = 17/72
Solving the equation above,
((x+1) + x) / (x)(x+1) = 17/72
If we take the numerators of both sides of the equation,
(x+1) + x = 17
The value of x from the equation is 8 and x+1 would be 9. Thus, the answer would be 8 and 9.
