X-5y=33
5x-6y=70
solve the system by the addition method

For this case we have the following system of equations:

We multiply the first equation by -5:

Thus, we have the equivalent system:

We add the equations:

We find the value of the variable "x":

Thus, the solution of the system is:

b 1: 45 am

step-by-step explanation:

its that because if it was in the pm it would be 1345

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 %
