To find how many three-digit numbers are divisible by 87, we will follow these steps:Step 1: Identify the smallest three-digit number divisible by 87 The smallest three-digit number is 100. To find the smallest three-digit numb
We see that x≠0 and x≠5, as x=0 does not yield a three−digit integer and x=5 yields a number divisible by 5. The second condition is that the sum 2x+y<20. When x is 1, 2, 3, or 4, y can be any digit from 0 to 9, as 2x<10. This yields 10(4)=40 numbers. ...
BThese three digit numbers are of the form xyx. We see that x≠q0 and x≠q5, as x=0 does not yield a three-digit integer and x=5 yields a number divisible by 5.The second condition is that the sum 2x+y20. When x is 1, 2, 3, or 4, y can be any digit from D to 9,...
