You can solve this problem by using the following rule of three:
 42 s ----> 0.5 DVD
 x ----> 1 DVD
 Clearing x:
 x = (1 / 0.5) * (42)
 x = 84 s (time to complete a DVD)
 Then, we have the following conversion:
 1min = 60s
 So:
 x = (84/60)
 x = 1.4 min
 The rate is then:
 rate = 1 / 1.4 = 0.71 DVD / minute
 Answer:
 Jaytree's "ripping rate" in DVDs per minute is
 0.71 DVD / minute

olasank [31]
1/2 + 3/x = 3/4
multiply everything by x
1/2x + 3 = 3/4x...subtract 1/2x from both sides
3 = 3/4x - 1/2x
3 = 3/4x - 2/4x
3 = 1/4x...multiply both sides by 4
4 * 3 = x
12 = x

Can anyone help me with this?0​
sergeinik [125]

Answer:

C) (y - 1)(y - 5)

Step-by-step explanation:

Hi there!

First you separate your expression into groups.

(y^2-5y)(-1y+5)

Now we take the common multiple out of each.

y(y - 5)-1(y - 5)

Since we have two (y - 5)s, we can pull it out of the equation as its own common multiple.

After we do that, we are left with y - 1. (we got this from taking the common multiples out)

Now we are just left with (y - 5)(y - 1)

Hope this helped!

Vanyuwa [196]
State tax is computed by first subtracting the amount of exemptions (5*$1000=$5000) from annual income and then multiplying it by the state tax.

($18150-$5000)*5%= $657.50

MrRissso [65]
I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
