Dominoes are small rectangular tiles with dots called spots or pips embossed at both halves of the tiles. a standard "double-six
" domino set has 28 tiles: one for each of the unordered pair of integers from (0,0) to (6,6). in general, a "double-n" domino set would consist of domino tiles for each unordered pair of integers from (0,0) to (n,n). determine all values of n for which one constructs a ring made up of all the tiles in a double-n domino set.
Cost of airplane toy = $4.84 let x be the cost of the toy car cost of airplane toy is 4 times the cost of toy car; it means 4x = $4.84 x = 4.84 / 4 x = 1.21 Thus, the cost of toy car is $1.21.
