The number 19 is a prime number, which means it is only divisible by 1 and itself.
In the case of 19, it is a prime number because it has only two distinct factors: 1 and 19. This means that there are no other whole numbers that you can multiply together to obtain 19.
To illustrate this further, let's check all the possible pairs of numbers that could potentially multiply to 19:
1 * 19 = 19
As you can see, the only combination of two numbers that yields 19 as their product is 1 and 19.
Therefore, 19 cannot be expressed as the product of two different whole numbers.

The original price of the item is given by the equation A = $ 93.75
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the original price of the item be represented as A
Now , the equation will be
The discount percentage of the item = 20 %
The discounted sale price of the item = $ 75
So , original price - ( 20/100 ) original price = discounted price
Substituting the values in the equation , we get
A - ( 20/100 )A = 75
( 80/100 )A = 75
Multiply by 100 on both sides of the equation , we get
80A = 7500
Divide by 80 on both sides of the equation , we get
A = $ 93.75
Hence , the original price is $ 93.75
