Divide both sides by 8 to find x:
-104/8=8x/8
=-13
Answer:
The teams can be placed in 479,001,600 ways.
Step-by-step explanation:
To solve this question, we want to know in how many ways 12 elements can be arranged.
Number of possible arrangements of x elements:
The number of possible arrangments of x elements is given by:

In this question:
12 teams, so arrangment of 12 elements.

The teams can be placed in 479,001,600 ways.
48. 40% of 80 is 32. 80-32=48. Which means there are 32 boys and 48 girls.
If the speed of the stream is x
Time is given by d/r , where r is the rate and d is the distance;
Rate for upstream = (15-x) mph and that of down stream is (15 +x) mph
The time taken will be the same;
Thus; 2/(15-x) = 4/(15+x)
cross multiplying;
30 +2x = 60 -4x
6x = 30
x =5
Therefore the rate of the river is 5 mph
Lol what do I answer here
