Singer a and singer b had the two top-grossing concert tours for a certain year, together generating $431 million in ticket sales. if singer b took in $23 million less than singer a, how much did each tour generate?
singer a generated $
in ticket sales and singer b generated $
million.

Singer A  $227 million and Singer B $204 million.

Step-by-step explanation:

Let singer A generate $a millions  and singer B $b millions.

So we have the equations:

a + b = 431

a -  b = 23

Adding the 2 equations:

2a = 454

a = 227

and b = 431 - 227

= 204.

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
