Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049
Answer: x=3

x=3
Answer:
This is the identity property of addition which states that when you add zero to a number the results is the number itself.
Step-by-step explanation:
Hello,
Identity is a number<em> t</em> that when added to other numbers it gives the same number<em> t. </em>In mathematics, the additive identity is always 0. In this property a number is added to 0 where the sum is always the number. For example 0+ 96= 96.
Other properties in math that involve addition are the commutative property, associative property and the distributive property.
In the commutative property, when two numbers are added, the sum is the same regardless of the order of the addends. For example, 3+2=2+3
The associative property states that when three or more numbers are added, the sum is the same regardless of how the addends are grouped.For example (2+3)+4 = 2+(3+4)
The distributive property states that the sum of two numbers multiplied by a third number is equal to the sum of each addend multiplied by the third number. For example 2*(9+1)=2*9 +2*1.
Hope this Helps.
solve for by simplifying both sides of the equation, then isolation the variable.
r = 0
