Step-by-step explanation:
F and C, I think those are the only ones
None of them are irrational, the definition of an irrational number is a number that cannot be simplified, converted to a fraction, or has no pattern to it or is never ending. For example, a pi is an irrational number because it is never ending and has no pattern to it. Another example would be 0.21411446741354... irrational because it has no pattern to it and cannot be converted to a fraction.
Answer:
Step-by-step explanation:
<h2>
What we know</h2>
We know that Kate has 3/4 of a cake. She wants to cut the cake into 1/12 sized pieces.
<h2>What we need to know</h2>
We need to know how many slices of cake will she have?
<h2>Show your work</h2>
If Kate wants to cut 3/4 of her cake into 1/12 sized pieces, that would mean 1/4 of the whole cake is 12/12. If there are 3 of the 1/4 slices, then we would need to find out how much that is in twelfths by multiplying:
12 x 4 = 48
36/48 is equal to 3/4. If she is having 3/4, she is having 36 slices.
<h2>Check your work</h2>
To check our work we divide:
48 ÷ 12 = 4
<h2>Answer</h2>
Kate will have 36 slices of cake.

The answer is 5 books.
m - the number of books sold on Monday
t - the number of books sold on Tuesday
w - the number of books sold on Wednesday
<span>On Tuesday, she sold twice as many books as she did on Monday: t = 2m
</span><span>On Wednesday, she sold 6 fewer books than she did on Tuesday: w = t - 6
</span><span>During the three days Rachel sold 19 books: m + t + w = 19
</span>t = 2m
w = t - 6 = 2m - 6
m + t + w = 19
______
Substitute t and w in the third equation:
m + 2m + 2m - 6 = 19
5m - 6 = 19
5m = 19 + 6
5m = 25
m = 25 : 5
m = 5
