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

  • math - hmmm -

    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.

  • math -

    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
