Which term describes a fraction that has a variable or variable expression in its numerator, its denominator, or both?
2 answers:
<span>The right answers is B. Rational expression.
This is true given that the statement establishes a term that describes a fraction that has a <em>variable or variable expression</em> in its numerator, denominator or both, that is, this is the concept of the quotient of two polynomials called rational expression. Finally, we can get the following rational expressions that matches with this concept, namely:

Answer:
Constant of proportionality is 12
The cost of buying new bicycle changes 12 dollar per week
Step-by-step explanation:
we are given
The equation as
where
d represents the amount in dollars
w is number of weeks
now, we can compare it with
where
k is constant of proportionality
we can compare
and we get
k=12
So,
Constant of proportionality is 12
we can see that
So,
The cost of buying new bicycle changes 12 dollar per week
