1. A-Tunes requires a membership fee of $12 a month and $1 for each download.
matrenka [14]
<h3>Answer:</h3>

After 16 downloads the charges will equal each other.

<h3>Step-by-step explanation:</h3>

First set up an equation

x = Downloads

12 + 1x = 5 + 1.5x

Solve

12 + 1x = 5 + 1.5x <- Rewrite your equation

-5          -5            <- Subtract 5 from both sides

 8 + 1x = 1.5x       <- Simplify

      -1x    -1x         <- Subtract 1 from both sides

        8 = 0.5x      <- Simplify

        8 = 1/2x       <- Convert 0.5 to a fraction to make the next step easier

       16 = x            <- Multiply both sides by 2 to divide by

                                 a fraction

2z^4-10z^3+4z^2 factorable?
charle [14.2K]
Yes
factor out the 2z^2 in each term
(2z^2)(z^2-5z+4)
factor some more
z^2-5z+4
find what 2 numbers multiply to get 4 and add to get -5
the numbers are -1 and -4
(z-1)(z-4)

the factored form is
(2z^2)(z-1)(z-4)

g100num [7]

Answer:

Bag 2

Step-by-step explanation:

Given

Bag 1:

14\ ounce = 3.50

Bag 2:

24\ ounce = 5.28

Required

Which is a better buy

To get which buy is better, we first get the unit price of each bag.

Unit\ Price = Amount/Size

For bag 1:

Unit\ Price = 3.50/14

Unit\ Price = 0.25

For bag 2:

Unit\ Price = 5.28/24

Unit\ Price = 0.22

The best buy is the one with smaller unit price

Hence, bag 2 is better to buy
