Find the solution of the system of equations.
10x + y = 16
-10x + 5y = 50

x= 0.5 y=11

Step-by-step explanation:

solve like simultaneous equations

(adding the equations together as that is how you get rid of the x values)

so you are left with 6y= 66

y=11

now substitute y into one of the equations (doesn't matter which)

10x + 11= 16

10x= 5

x=0.5

answer: i think it is (1,-2)

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 %
