You would divide 7 by 3. 3 Times 2 = 6
Pit the remaining over 3. 1 4/3
The value of the expression C(6,3) is 20
<h3>How to evaluate the expression?</h3>
The expression is given as:
C(6, 3)
This means 6 combination 3.
And it can be written as:
Apply the combination formula
Evaluate the expression
Hence, the value of the expression C(6,3) is 20

B is the answer it is the only othe shplape
Answer:
Solution (-2, 7)
Step-by-step explanation:
2x + 3y = 17 (1)
5x + 6y = 32 (2)
Using elimination method
Multiply (-2) to the equation (1)
-4x - 6y = -34
Now you have 2 new equations
-4x - 6y = -34
5x + 6y = 32
----------------------------Add
x = -2
Substitute x = -2 into 2x + 3y = 17
2(-2) + 3y = 17
- 4 + 3y = 17
3y = 21
y = 7
Solution (-2, 7)
In a system of equations ax + b = 0, a≠ 0, the equation x = -b/a is referred as a non-trivial solution.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
The system Ax + b = 0 has the following solutions:
- The zeros, which is the trivial solution.
- x = -b/a, which is the non-trivial solution.
