You have to divide 54 by 4.5 to get the rate per hour then you times that by six and you get 72 so it would look like this 
54/4.5=12*6= 72 so your answer would be 72

First, we divide 54 by 4.5 to find out how many miles she can ride in 1 hour, then multiply that to 6 to find how many miles she can ride in 6 hours. 54 / 4.5 = 12, and 12 x 6 = 72, so she can ride 72 miles in 6 hours. :)

Taya2010 [7]
We know that Bonnie complete her paper route in 45min. So, in 1min she can complete:

\frac{1}{45} of her paper route.

We need to know <span>how long it would take Jean alone, then we will call this time x. Working together they last 18min, so </span>in 1min they can complete:

\frac{1}{18} of the paper route.

The paper route working together satisfies the following equation:

\frac{1}{18} = \frac{1}{45} + \frac{1}{x}

Solving this equation:

\frac{1}{x} = \frac{1}{18} - \frac{1}{45} =  \frac{45-18}{810} =  \frac{27}{810}
x = \frac{810}{27} = 30min

Finally:
It takes 30min to complete the paper route by Jane alone.

Write an equation in slope intercept form that describes a line with a slope of 3 and containing the point (5,-1)
soldier1979 [14.2K]

Answer:

<h2>         y = 3x - 16</h2>

Step-by-step explanation:

Equation of line with a given slope of a and containing a given point (x₀, y₀):

y - y₀ = a(x - x₀)

a = 3,  x₀ = 5,  y₀ = -1

So:

y - (-1) = 3(x - 5)  

y = 3x - 15 - 1

<u>y = 3x - 16</u>
