At a stock exchange there were a total of 10,000 shares sold in one day. stock a had four times as many
shares sold as stock b. the number of shares sold for stock c was equal to the sum of the numbers of
shares sold for stock a and stock b. how many shares of each stock were sold?
shares of stock a were sold,
were sold.
shares of stock b were sold, and
shares of stock
what’s the answer

Share sold by Stock A = 4000, Stock B = 1000 and Stock C = 5000

Step-by-step explanation:

Total sold sold = 10000

i.e. ....(1)

Shares sold by stock A = 4 × Shares sold by stock B

i.e. ....(2)

Shares sold by stock C = Shares sold by stock A + Shares sold by stock B

i.e. ....(3)

substituting value of from (2) in (3) we get

....(4)

substituting value of and from (2) and (4) in (1) we get

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
