Find the value of x ​

x = 4

Step-by-step explanation:

10x + 140 = 180

10x = 40

x = 4

x = 4

Step-by-step explanation:

I did 140 + 10x = 180

Then I solved by subtracting 180 - 140 to get:

10x = 40

Next you divide 10 on both sides to get 4 as x

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 %
