Answer:
it is application of the multiplication property of equality
Step-by-step explanation:
You can use "cross products" to solve any proportion. What looks like a "cross product" is just application of the multiplication property of equality. That property says the variable value is unchanged if both sides of the equation are multiplied by the same value.
For your fraction, the "cross product" is what you get when you multiply both sides of the equation by 500.

Note that the next step here is to divide by the x-coefficient, the 5 that was in the left-side denominator.

Please also note that this is exactly the same result you would get by multiplying the original equation by the original denominator of x.
Domain: 
Range: 
Explanation:
The function is 
The domain of a function is the set of all input values for which the function is well defined. Generally, domain consists of all x-values of the function. Hence, the function
is defined in the interval
.
The range of a function is the set of output values obtained by substituting the value of x in the function. Hence, the function
is defined in the interval
.
The full length of the circumference is
C = 2πr
C = 2π*100 m ≈ 628.32 m
1/3 that distance is (628.32 m)/3 ≈ 209.44 m
Maile walked about 209.4 m.
Answer:
y=3
Step-by-step explanation:
4y-8+4=8
4y-4=8
4y-4+4=8+4
4y=12
4y/4=12/4
y=3
