A prime number is a number greater than one and can only be divided by 1 and itself. The result is always a whole number, i.e. no fractions, decimals, remainders.

Example: 
2 can only be divided by 1 and itself 
3 can only be divided by 1 and itself. 

4 however, can be divided by 1 or 2 or itself 

1 is not a prime number since it is not greater than one.

Prime numbers are positive integers that cannot be factored. Meaning it cannot be divided by any other number but 1 and itself.

For example:
2 is a prime number. It can only be divided by 1 and 2.
4 is not a prime number. Because it can be divided by 1, 2, and 4.

Take note: prime numbers are POSITIVE integers only.

Additional information about prime numbers:
* The only even prime number is 2. The rest even number are not prime numbers because it can be divided by 2.
* zero and 1 are not considered prime numbers
* numbers that are not prime numbers are called composite numbers.

How do you get why by itself in this equation? 4x+5y=5

Alja [10]

Answer:

first we get y on one side by itself.

4x+5y=5

we'll move x to the other side.

4x-4x+5y=5-4x

simplify.

5y=5-4x

now we get rid of the coefficient on y.

5y/5=(5-4x)/5

simplify.

y=5/5-4x/5

y=1- $\frac{4}{5}x$

The answer is $y=1-\frac{4}{5}x$

Points F,G, and H are collinear such that FG:FH=2/3.If a directed line segment begins at F(-3,2) and ends at H (-3,7), find the

Nana76 [90]

We consider the x- and y-coordinates separately. Let the coordinates of G be (x, y). Now considering the x-coordinates:
FG/FH = (x - (-3)) / (-3 - (-3)) = 2/3
x + 3 = (2/3)(6)
x = 1
For the y-coordinates:
FG/FH = (y - 2) / (7 - 2) = 2/3
y - 2 = (2/3)(5)
y = 16/3
Therefore the coordinates of G are (1, 16/3).

Stephan has a piece of wood that measures 18 inches long and 12 inches wide. He wants to make a tray with sides 2 inches high. M

valkas [14]

Answer:

i. No, Maurice statement is wrong.

ii. Stephan does not have sufficient pieces of wood to make the tray because the square inches required is more than what he has.

Step-by-step explanation:

Stephan's piece of wood measures; 18 inches in length and 12 inches in width.

Since the piece of wood has a shape of a rectangle,

the area of the piece of wood = length × width

= 18 × 12

= 216 square inches

According to Maurice's statement, he could make a tray that has a base of 1012 inches by 1012 inches.

The base has the shape of a square, so that;

the area of the base = length × width = $length^{2}$

= 1012 ×1012

= 1024144 squared inches

This shows that Stephan does not have sufficient wood to make the tray because the square inches required is more than what he has.
