Answer:
You <u>solve</u> the equation.
Step-by-step explanation:
The process of finding variable values that make the equation true is called <em>solving</em> the equation.
X, y - the numbers
The product is 18.

The quotient is 2.

Substitute 2y for x in the 1st equation:

The numbers are
6 and 3 or
-6 and -3.
Permutation: In a race of 10 students, find the number of ways students can finish 1st, 2nd, and 3rd. In this case the order matters, so it is a permutation.
10 x 9 x 8 = 720 ways
Combination: In a class of 10 students, find the number of ways a group of 3 students can be selected to win a prize. In this case the order doesn't matter, so it's a combination.
10 x 9 x 8 / (3 x 2 x 1) = 120 ways
Answer:

Step-by-step explanation:

(3/4)^4 = 81/256
1 ÷ 81/256 = 256/81
So;
