A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess board on the second square the king would place two grains of wheat, on the third square, four grains of wheat, and on the fourth square eight grains of wheat If the amount of wheat is doubled in the way
on each of the remaining squares, how many grains of wheat should be placed on square 147 Also find the total number of grains of wheat on the board at this time
and their total weight in pounds (Assume that each grain of wheat weighs 1/7000 pound)
How many grains of wheat should be placed on square 14?
grains

final answer is : )

i think the answer is fried chicken ; >

its kind of blurry. can you put a clearer pic?

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
