Answer:
It gives you 28 different 10-digit numbers
Step-by-step explanation:
The leftmost position digit can not be 0 --- hence, it is 1, since there is no other possibilities.
The rightmost position (the "ones" position) must be 0 to provide an even number.
Hence, you have 8 remaining positions to fill with six ones and two zeros by an arbitrary way.
You can place two digits of zero among 8 positions by 
= 
different ways = 4*7 = 28 different ways,
Answer:
Step-by-step explanation:
Integers are irrational numbers. A natural number is a rational number. An irrational number is a real number. Zero is a natural number.

<h3>Answer:</h3>
c) there are infinitely many solutions
<h3>Explanation:</h3>
Add x to the <em>first equation</em> to put it in standard form:
... x + y = 3
Divide the <em>second equation</em> by the common factor of all terms, 2, to put it in standard form:
... x + y = 3
These two equations describe the same line. Every point on the line is a solution to both equations, so there are infinitely many solutions. (We say these equations are "dependent.")
