What is an attribute of a fractional equation?
2 answers:
Answer:
<h2>There is a variable in the denominator of at least one involved fraction.</h2>Step-by-step explanation:
The actual definition of a fractional equation could be:
In words, fractional equations are those which has variables in the denominator of a fractional term, that doesn't mean that all fractions must have a unknown denominator, but at least one of the denominators should have a variable.
Therefore, according to its definition, the right answer is third option.
<em>In addition, other options don't make sense, multiple variables is not necessarily the case for fractional equations. Similarly, not all denominators must have variables. And, having variable only in the numerators don't define the equation as fractional.</em>

The width would be calculated like this:
you draw an equilateral triangle in the middle with sides or 2r(56mm). The based on pythagorean theorem u know that
h=rad(56^2-28^2)=48.497
28+28+h=104.497
The area would be S=l*w which is 11703.7113mm

Answer:
The American population was 20% of the British population.
Step-by-step explanation:
Let us call the american population,
the British population before the migration, and
the population that migrated from America to Britannia.
Now, the population that migrated was 20% of the american population:
,
and the same population increase the British population by 4%:
Combining equation (1) and (2) we get:
Thus, the American population was 20% of the British population.
