I'm a 3 digit number,my 10's digit is 5 more than my 1's digit, my 100's digit is 8 less than my 10's digitI

Answer 1

194

Answer 2

Let the 3 digit number be a b c
b = c + 5; a = b - 8
Now a + 8 = b so a = 1 which leads to b = 9 which ,in turn , leads to c = 4
The 3 digit number is thus 1 9 4

Answer 3

First assign each digit a variable; your three digit number will be XYZ, where X represents the hundreds digit, Y represents the tens digit, and Z represents the ones digit.

From the problem, we are given the following two equations:
Z+5=Y
X+8=Y

Remember that all digits must be positive, and must represent a number between 1 and 9. If you look at the second equation, X+8=Y, you realize that the only way for Y to fulfill this requirement is if X=1. Thus, X=1 and Y=9. You then plug Y=9 into the first equation, and find that Z=4.

Thus,
X=1
Y=9
Z=4

Answer 4

Let be the three digit number in decimal expansion.

Given:

b = c + 5
b = a + 8
a: nonzero

Since b = a + 8, and a is nonzero, a must equal 1 and b must equal 9. Then c must equal 4.

Thus = 194.
