Unit conversion is a way of converting some common units into another without changing their real value. The approximate value in US dollars is $210.53.
<h3>What is unit conversion?</h3>
Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.
The exchange rate of Mexican pesos for US dollars is approximately 19 pesos for 1 dollar. Therefore, we can write,
19 pesos = 1 dollar
1 pesos = 1/19 dollar
if Lynn exchanges 4,000 pesos for US dollars, then the approximate value in US dollars will be,
4,000 pesos = 4000/19 = 210.53 dollars
Hence, the approximate value in US dollars is $210.53.

Solution:
we are given that
The difference of two numbers is equal to 0.6.
Let the numbers be x and y so we can write
Their quotient is also 0.6.
so we can write
Now solve these two equations together we get
Hence the numbers are -1.5 and -0.9
Given:
To find:
The interval(s) on which the given function is positive.
Solution:
We have,
For zeroes, 
-1 and 5 divide the number line in three parts 
.

So, the function is positive for interval and .
We can say that the function is positive for interval x < -1 and x > 5.
Therefore, the correct option is B.
6x³y + 6xy − 12x² − 12 = 6(xy-2) * (x²+1)
(x²+1) is a factor of 6x³y + 6xy − 12x² − 12
Answer:20
Step-by-step explanation:
x/24=5/6
multiply both sides by 24
x=(5*24)/6
simplify
x=5*4
x=20
