Put the equation in standard form with a positive x coefficient y + 3 = 3(x+5)

3x - y = - 12

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given

y + 3 = 3(x + 5) ← distribute

y + 3 = 3x + 15 ( subtract y from both sides )

3 = 3x - y + 15 ( subtract 15 from both sides )

- 12 = 3x - y, thus

3x - y = - 12 ← in standard form

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 %
