How many 5-digit palindromes contain only even digits?

34kurt

Answer:

The correct answer is - 900

Step-by-step explanation:

A palindrome is a positive integer that is same whether read from left to right or from right to left. For example, 123321 palindromes.

An n-digit palindrome is determined from the first n/2 digits if n is even, and from the first n+1/2 digits if n is odd.

Therefore, if n is even, there are 9×10⁽n⁻²/²⁾ palindromes; and if n is odd, there are 9×10⁽n₋²/²⁾ palindromes. where n is number of digits.

For n=5 , there are 9×10²=900 palindromes

The variable z is inversely proportional to x. When x is 16, z has the value 0.9375.

Setler [38]

Since z is inversely proportional to x, when x increases by a factor of 26/16, z will be multiplied by the inverse of that factor: 16/26

$z=\dfrac{16}{26}\cdot 0.9375=0.5\overline{769230}=\dfrac{15}{26}$

Answer:

I could do 1 and 3

1) 2x-3y=-2 ....1

2x+y=14......2

=-4y=-16

y=4

Substitute (y=4) into equation 1

2x-3 (4)=-2

2x-12=-2

2x=-2+12

2x=10

×=5

3) 5x+5y=20....1

-3x+5y=4......2

=8x=16

x=2

Substitute (x=2) into equation 1

5 (2)+5y=20

10+5y=20

5y=20-10

5y=10

y=2
