I’m having trouble figuring this out

The total cost to build the deck equals the cost of the materials and the cost of the carpenters wage.

Let "y" equal the total cost and let x equal the hours.

Algebraically: y= 30x+1000

substitute 1480 for the total cost "y"

1480=30x+1000

1480-1000=30x

480=30x

480/30= 30/30x

x=6

or it will take six hours to build the deck.

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

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 %
