The number of blocks had 9 in the ones place. the number in the hundreds place is one more than the numbers in the tens place. those two numbers equal 11. how many blocks are there

We have to determine the number of blocks. We know that that number have 9 in the ones place. It also has the number in the hudreds place ( x ) which is 1 more than the number in the tens place ( y ). And: x + y = 11. Another equation is: x = y + 1. Therefore y + 1 + y = 11; 2 y = 11 - 1; 2 y = 10; y = 10 : 2; y = 5 and x = 5 + 1 = 6. There are 659 blocks.
