Answer:

Step-by-step explanation:

4(x+6)/(x-2)*(x+10)/24(x+6)

First we do 4(x+6)

4x+24

Then we do 24(x+6)

24x+144

So we plug it in

4x+24/x-2*x+10/24x+144

Answer:

3.8

Step-by-step explanation:

$58-5x=30x-75$

The town librarian bought a combination of new-release movies on DVD for $20 and classic movies on DVD for $8. Let x represent t

Galina-37 [17]

Answer:

x = 1, y = 60

Step-by-step explanation:

Value of new-releases (x) = $20 each

Value of classic (y) = $8 each

Total budget = $500

Equation : 20x + 8y = 500

The librarian wants to purchase maximum DVDs. She can get more DVDs of classic movies for $8 as they are less costly.

Lets assume the librarian buys at least one new-release DVD.

x=1

20x + 8y = 500

8y + 20(1) = 500

y = 60

<em>Therefore, in a budget of $500, the librarian can purchase 60 classic movies and 1 new-release.</em>

If f(x) = 5x, what is f -1 (x) ?

Gala2k [10]

Answer:

$f^{-1}(x) = \frac{x}{5}$

Step-by-step explanation:

$f^{-1}\left( x\right) =y\Longleftrightarrow f\left( y\right) =x$

…………………………

f(y) = x

⇔ 5y = x

$\Longleftrightarrow y =\frac{x}{5}$

$\Longleftrightarrow f^{-1}(x) = \frac{x}{5}$

Shelia went snowboarding. She spent $118 for the pass and snowboard rental. The snowboard rental cost $25. What percent of the t

padilas [110]

I believe the answer is about 78.81% because you subtract 25 from 118. Then that would be 93. 118 is equal to the 100% and 118 divide by 1.18 equals 100. Divide 93 from 1.18 gives you the answer
