and one day and he traveled five times the sum of the number of hours Brian traveled and 2 together they travel 20 hours find th
Jet001 [13]
Let X represent the number of hours you travelled
Let B represent number of hours Brian travelled 

Equation 1 is X + B = 20 (since combination of number of hours you and Brian travelled equal to 20 hours)
Equation 2 is M = 5B (since you travelled five times more than the amount in which Brian travelled)

Plug Equation 2 into Equation 1 (replacing M with its value)
5B + B = 20

Rearrange equation to make B its subject (find B)
6B = 20
6B/6 = 20/6
B = 3(1/3)
Brian travelled a total of 3(1/3) (three and a third) hours. 
(1/3) of an hour = 60/3  or 60*(1/3) = 20mins
Brian travelled a total of 3hrs & 20mins. 

Plug B value back into Equation 1 
M + B = 20
M + 3(1/3) = 20

Rearrange equation to make M its subject (find M)
M = 20 - 3(1/3) = 16(2/3) 
You travelled a total of 16(2/3) (sixteen and two-thirds) hours.
(2/3) of an hour = 60/3*2 or 60*(2/3) = 40mins
You travelled a total of 16hrs & 40mins.

How to find the asymptotes of a hyperbola?
stellarik [79]
Vertical asymptote:
Find the restriction on x. This is the easiest of the three asymptotes you will need to find (even if only two can show at a time). As a hyperbola is in the form: \frac{1}{x}, you only need to find the restriction on the denominator, namely denominator can never be zero. Hence, let the denominator equal to zero to find the vertical asymptote.

Horizontal asymptote:
Find the restriction on y. To do this, you need to simplify the top and bottom to its lowest terms. If it simplifies to a form such as: a + \frac{b}{x}, then the horizontal asymptote becomes y = a. You need to think to yourself, as x grows to infinite, and shrinks to negative infinite, what happens to the function? Does it slowly curve to a stop?

Oblique asymptote:
This is a pretty rare kind, but it still exists, so don't be naive to this sort of asymptote. This is a form of horizontal and vertical asymptote, only it's at an angle. That is, this asymptote is a set of x and y-coordinates that work in unison to produce a curvature or line.

Let's consider: f(x) = \frac{x^{2} - 6x + 7}{x + 5}

Now, in normal term, a horizontal asymptote would have a degree higher in the denominator than in the numerator. However, it's flipped in this case.

Now, you will need to long divide this set of polynomials to yield a straight y = x line, except it's been moved 11 units to the right to yield a y = x - 11 line.

Remember: these exist because the highest power is in the numerator and not the denominator.

Sana bought a dress for $32.99 and two purses. The total cost for the three items was $57.97. What was the cost for one purse?
faust18 [17]

Answer:

$12.49

Step-by-step explanation:

cost of two purses = $57.97 - cost of dress = $57.97 - $32.99 = $24.98

cost of one purse = $24.98 ÷ 2 = $12.49
