What are the steps and answer to 1/3k+80=1/2k+120

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
