The sum of twice a number and a larger number is 145. The difference between the numbers is 55. Let x represent the smaller number and y represent the larger number. Which equations represent the situation? Check all that apply.

2x+y=145 and x-y=55.

Step-by-step explanation:

Let x represent the smaller number and y represent the larger number.

ATQ,

The sum of twice a number and a larger number is 145.

2x+y=145 ...(1)

The difference between the numbers is 55.

x-y=55 ...(2)

Hence, the two equations that represent the situation are 2x+y=145 and x-y=55.

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 %
