It takes you 45 minutes to clean the fish tank and it takes your sister 30 minutes. how long does it take the two of you working together to clean the fish tank

Answer:

My 1 minute work =\frac{1}{45}

My sisters 1 minute work =\frac{1}{30}

My and My sister's 1 minute work =\frac{1}{45}+\frac{1}{30}

                                                        =\frac{5}{90}

                                                        =\frac{1}{18}

\therefore Me and My sister will finish the work in \frac{18}{1} =18 minutes

Answer:

6y² - 20y + 6

Step-by-step explanation:

Use FOIL method

(3y - 1)(y-3) = 3y*y + 3y*(-3) + (-1)*y + (-1)*(-3)

                 = 3y²- 9y - y + 3    {add the like terms}

                = 3y² - 10y + 3

2(3y - 1)(y - 3) = 2 ( 3y² - 10y + 3)

                      = 2*3y² - 2*10y + 2*3

                      = 6y² - 20y + 6

The bus fare without a coupon book is $1.50 a coupon book cost $30.00, with the coupon book the fare is reduced $0.50. How many
valentina_108 [34]

Answer: the bus would be used 30 times for the monthly costs to be the same.

Step-by-step explanation:

Let x represent the number of times in a month for which the bus must be used so the total monthly cost is the same with the book as it is without it.

The bus fare without a coupon book is $1.50. This means that the total monthly cost of using the bus for x times without a coupon book is 1.5x

A coupon book cost $30.00 and with the coupon book, the fare is reduced $0.50. This means that the total monthly cost of using the bus for x times with a coupon book is

0.5x + 30

For the monthly costs to be the same,

1.5x = 0.5x + 30

1.5x - 0.5x = 30

x = 30
