a c-shaped tile (2 in the top row, 1 on the second, 2 on the bottom) can be placed on a number chart so that the sum of the numbers covered is 29. show how this can be done
Let the upper left be at n. Then the tiles add up to
n + (n+1) + (n+10) + (n+20) + (n+21) = 29
5n+52 = 29
Evidently I misunderstand the number chart. I figured it was a grid of numbers, 10 per row.
lets say you have a 100 number chart you put the c shaped tile on it the numbers that are covered add up to 29 the closest i have got is 28 or 30
