Answer:
99.
Step-by-step explanation:
A palindrome number is one that can be read in the same way both from the front and from the back. A clear example is the number 242, which starts and ends in the same way from the front or back.
Between 10 and 100, there are 9 palindromes, from 11 to 99. In turn, between 100 and 200, 200 and 300 and so on, each hundred has within it 10 palindromes (101, 111, 121, 131, 141 , 151, 161, 171, 181 and 191, for example).
Therefore, considering the 9 hundreds between 100 and 1000, there will be 90 palindromes, which added to the 9 between 10 and 100 give a total of 99 palindromes.
it going to be 18 because the number is two less than ones digits and the sum of the digit is 8
Answer:
7.6
Step-by-step explanation:
Answer:
x = 2, y = 29
Step-by-step explanation:
3y+19 = 106
3y = 106-19
3y = 87
y = 87/3
y = 29
2x+9 = x+11
2x-x = 11-9
x = 2
