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:

<h3>Answer:</h3>
2/15
<h3>Explanation:</h3>
There are 8C2 = 28 ways to choose 2 dimes from the 8 dimes in Annie's purse. There are 21C2 = 210 ways to choose 2 coins from the 21 coins in Annie's purse.
Of the 210 ways to choose 2 coins, 28 of the choices will result in 2 dimes being chosen. The probability of choosing 2 dimes is 28/210 = 2/15.
_____
<em>Comment on nCk</em>
The number of ways to choose k objects from n, when order does not matter, is ...
... n!/(k!(n -k)!)
For the computations above, we have ...
... 8C2 = 8·7/(2·1) = 28
... 21C2 = 21·20/(2·1) = 210
Answer:
Jill would pay 5.945
Reason:
You add up 5.49 and 6.29 and get 11.78. Then you would divide that by 4 and get 2.945. If Jill were to pay the tip then they would have to pay three dollars would add three dollars onto their 2.945 and they would have to pay 5.945 instead of 2.945.

Answer:
175/48
Step-by-step explanation:
Convert 8 6/8 and 2 2/5 to fractions
8 6/8 = 70/8 ; 2 2/5 = 12/5
Now, we have : 70/8 : 12/5
= 70/8 x 5/12
= 70x5/8x12
=350/96
Simplify the fraction, we get 175/48
