¿cual es la solucion de la siguiente ecuacion (10+2x +x= -x +18)?

x=2

Step-by-step explanation:

x = 2

Step-by-step explanation:

(10 + 2x + x = - x + 18)

10 + 2x + x = - x + 18

10 + 3x = - x + 18

10 + 3x + x = - x + x + 18

10 + 4x = 18

10 - 10 = 4x = 18 - 10

4x = 8

4x ÷ 4 = 8 ÷ 4

x = 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 %
