Answer:
ONE: x = 10
Step-by-step explanation:
3x + 6 = -1 - 3 + 4x
3x + 6 = -4 + 4x |subtract 6 from both sides
3x = -10 + 4x |subtract 4x from both sides
-x = -10 |change the signs
x = 10
Answer:
A. 1, 287 ways
B. 154,440 ways
Step-by-step explanation:
A. We want to choose 5 objects from a total 13, without considering the order in which they are chosen.
The correct way to do this is by using the combination formula since order is not considered;
Thus we have ; 13 C 5 read as 13 combination 5;
Mathematically, n C r is ; n!/(n-r)!r!
Thus, we have ;
13!/(13-8)!8! = 13!/5!8! = 1,287 ways
B. By considering order, we shall be using the permutation formula;
Mathematically n P r = n!/(n-r)!
Read as n permutation r;
Using the numbers involved, we have ; 13 P 5
= 13!/(13-5)! = 13!/8! = 154,440 ways
Answer:
250 and 2 because i think 250 multiply by 2 is 500
The answer would be B.
For these, you plug in 8 where there ia a variable. 2(8)-1=15
