Answer:A composite number is divisible by at least three numbers. Every counting number except 1 is either prime or composite. The reason 1 is neither is that it's divisible by only one number, which is 1. Remember the first four prime numbers: 2, 3, 5, and 7.

Answer: x = 5, y = 2/5
Step-by-step explanation:
We have the system of equations:
6*x + 5*y = 32
2*x + 5*y = 12
To solve it, we can start by isolating one of the variables in one of the equations.
Because in both of them we have the term 5*y, i will isolate 5*y in the second equation:
5*y = 12 - 2*x
Now let's replace it in the first equation:
6*x + (12 - 2*x) = 32
Now let's solve it for x
6*x + 12 - 2*x = 32
(6*x - 2*x) = 32 - 12 = 20
4*x = 20
x = 20/4 = 5
Now we know the value of x, we can replace it in the equation:
5*y = 12 - 2*x
to find the value of y.
5*y = 12 - 2*5
5*y = 2
y = 2/5
Then the solution of the system is x = 5, y = 2/5

Step-by-step explanation:
Answer: Choice B) (24,10)
---------------------------------------------------------
Work Shown:
2x - 4y = 8
2( x ) - 4y = 8
2( 3y-6 ) - 4y = 8 ... notice x has been replaced with 3y-6
2(3y)+2(-6) - 4y = 8
6y-12 - 4y = 8
2y-12 = 8
2y-12+12 = 8+12 ... add 12 to both sides
2y = 20
2y/2 = 20/2 ... divide both sides by 2
y = 10
If y = 10, then
x = 3y-6
x = 3*10-6 ... replace y with 10
x = 30-6
x = 24
Put together, the solution is (x,y) = (24,10)
which is why the answer is choice B
As a check, we can plug (x,y) = (24,10) into each equation
x = 3y-6
24 = 3*10 - 6
24 = 30 - 6
24 = 24 ... true equation
and similarly for the second equation as well
2x-4y = 8
2*24 - 4*10 = 8
48 - 40 = 8
8 = 8 ... true equation
Both equations are true when (x,y) = (24,10) so the solution is confirmed
