Answer:
As a fraction, A is 3/8 concentrate in final product and B is 4/11.
A is, in other words, 33/88, and B is 36/88 concentrate in the final mixture.
So Mixture B is stronger, slightly.
Note that in order to make the fractions the same denominator, we had to 'expand' each fraction with the denominator of the other fraction. After that, the numbers are really easy to compare.
Ok so put the a factors together first
4a + 19 - 3a - 7 = a + 19 + 7
a + 19 + 7 = a + 26
B because you hace to multiple
Answer:
56 ways.
Step-by-step explanation:
This question is solved by using combinations and permutations chapters in the math book.
To put it simply, we need to find the number of 3 horse combinations we can make from 8 horses. This requires the combinations formula:

here n is the total number of objects to choose from, and r is the number of objects we require in the combination or group.
Since there are 8 horses, n= 8
Since we need to choose only 3 of them, and order does not matter, r= 3
Solving the equation above using these inputs gives us 56 unique ways we can choose the three winners.
