True or false if false explain why? some one help please?

1. if the whole numbers less than 10 is odd, then it must be a factor of 10





2. a whole number less than 10 that is a factor of 10 must be odd.





Part 2: are the following statements always, sometimes, or never true? explain





a. a whole number that is even and less than 10 is a factor of 6





b. a factor of six that is less than 10 is 7True or false if false explain why? some one help please?
1. if the whole numbers less than 10 is odd, then it must be a factor of 10





False, 3, 7, 9 are whole numbers less than 10, none of these is a factor of 10.





2. a whole number less than 10 that is a factor of 10 must be odd.





False, 2 is a whole number, less than 10, a factor of 10, and even.





Part 2: are the following statements always, sometimes, or never true? explain





a. a whole number that is even and less than 10 is a factor of 6





Sometimes true, 4 %26amp; 8 are whole even numbers, less than 10, neither is a factor of 6. 2 %26amp; 6 are whole even numbers, less than 10, both are factors of 6.





b. a factor of six that is less than 10 is 7





Never true. 7 is not a factor of 6.True or false if false explain why? some one help please?
1 - false. odd numbers less than ten are 1,3,5,7,9. Only 1,5 are factors of ten





2 - false. factors of ten less than ten are 1,2,5. 2 is not odd





a - never. even whole numbers less than ten are 2,4,6,8. 8 is not a factor of ten





b - never. factors of six are 1,2,3,6. Not 7





These statements all have two parts [also called if-then statements] First, find all numbers that make the first part true. Then, see if they also make the second part true. Good luck
1) False





3, 7 and 9 are odd whole numbers less than 10 but they are not a factor of 10





2) False





2 is less than 10 and a factor of 10 but it is not odd. It is even.





====================


a) Sometimes





2 and 3 are factors of 6 but 3 is not even.


1 and 6 are factors of 6 but 1 is not even.





Only 2 and 6 satisfies the statement.





b) NEVER





7 is not a factor of 6






1 is false b/c 7 is odd, but it is not a factor of 10





#2 is false b/c 2 is a factor of 10 but it is even,





pt 2 - a is sometimes true b/c 2 is a factor but 4 and 8 are not





b is false b/c 7 is not a factor of 6
1.


false---%26gt; the odd number %26lt; then 10 are 1,3,5,7,9 only five is a factor of 10.





2.


false 2 is a whole number less than and it is even.





part 2


a.


even number less than ten are-----%26gt; 2,4,6,8 sometimes true---%26gt; 2 and 6


b.


never true------%26gt; because 7 is not a factor of 6
