Please help! Please!!
Elza [17]
You can proceed like this,

650 kb for a pic
and 2200kb for song ( 650 + 1550)

total= 18150 kb  and 16 files

so, 650 kb each in both pic and song = 16 * 650= 10400

remaining = 18150-10400 = 7750 , which is contributed by  additional 1550 of songs that is  
7750/1550 = 5

so, a total of 5 songs and 11 pictures were  sold..

hope it helped

How do u simplify 5x^2-8x-12 subracted from -4x^2+2x-8
Nady [450]

Answer:

- 9x² + 10x + 4

Step-by-step explanation:

Calculate the subtraction as

- 4x² + 2x - 8 - (5x² - 8x - 12 ) ← distribute parenthesis by - 1

= - 4x² + 2x - 8 - 5x² + 8x + 12 ← collect like terms

= - 9x² + 10x + 4

A pair of dice are rolled. What is the probability of rolling 6 or less?
Allushta [10]

Answer:

1/36

Step-by-step explanation:

The probability of rolling a number less than 6 or 6 itself on one die is 1/6. A pair of dice would be the combined probability 1/6*1/6 which is 1/36. So there's a 1/36 chance of having both dice roll numbers less than 6 or 6 itself.
