Find what x and y are

x= 8

y = 21

Step-by-step explanation:

27 + 3y = 90

3y = 90 -27

y = 63/3

y = 21

x+ 90 +8x+18 = 180. { linear pair}

9x +108 = 180

9x = 180-108

x= 72/9

x = 8

x= 8  

y = 21

Step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
