Palindromes are numbers whose reverse is the same as the original number
There are twenty-five 5-digit palindromic numbers, that have digits that add up to 14
<h3>How to determine the count of 4-digit palindromes</h3>
The digit of the palindromic number is 5.
This means that:
- The first digit of the palindrome can be any of 1 to 7 (because 7 is half of 14)
- The second digit can be any of 0 - 6 (i.e. 7 digits)
- The third digit can be any of 9 digits
- The fourth digit must be the second digit (i.e. 1 digit)
- The last digit must be the first digit (i.e. 1 digit)
So, the total number of digits is:


Hence, there are twenty-five 5-digit palindromic numbers, that have digits that add up to 14

Answer:


Step-by-step explanation:
Represent Celsius with C and Fahrenheit with F.
So, we have:


Solving (a): Represent as a linear equation
First, we calculate the slope:

This gives:



The linear equation is then calculated using:

Where




Make F the subject


Solving (b): The value of F when C = 30
Substitute 30 for C in 



Look at where the lines intersect each other, if they do then you can use one of the coordinates. the lines that don’t touch means no solution
I dont believe there is any figure we can see, take a larger picture please
No, because with the parentheses, you distribute the 2 to both the x and the 5, making that equation 2x-10
