In your own words, explain to me what is absolute value? Make sure to talk about the definition of it, how you find it, and how it's different from just plotting an integer on a number line. You must provide 3 sentences or more.
Answer:
It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.
This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.
Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.
The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.

Why is taking a census better than taking samples in a survey?
I just need the ratio and the explanation, Lin, Diego, and Elena are competing to see who can finish their book the fastest.
Lin read the first 54 pages from a 270-page book in the first 3 days.
Diego read the first 100 pages from a 320-page book in the first 4 days.
Elena read the first 160 pages from a 480-page book in the first 5 days.
If they continue to read every day at these rates, who will finish first, second, and third? Explain or show your reasoning:
Answer: The answer to your question is:
1st Diego
2nd Diego and Elena ( both 15 days)
Step-by-step explanation:
Data
Lin 54 pages 270-page book 3 days
Diego 100 pages 320 page 4 days
Elena 160 pages 480 page 5 days
Process
Lin
54 pages ------------------- 3 days
270 page ----------------- x
x = (270 x 3) / 54
x = 15 days
Diego
100 pages ----------------- 4 days
320 -------------------- x
x = (320 x 4) / 100
x = 12.8 days
Elena
160 pages ------------------- 5 days
480 pages -------------------- x
x = (480 x 5) / 160
x = 15 days

The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
A hole needs to arrive at no less than 72 feet subterranean level. This implies it should be multiple 1/2 times its ongoing profundity. This profundity is addressed by the imbalance 4 ¹/₂ d < - 72, where d is the ongoing profundity of the burrow.
4 ¹/₂ d < - 72
Simplify the inequality, then we have
4 ¹/₂ d < - 72
4.5d < - 72
d < - 72 / 4.5
d < - 16
The ongoing profundity of the hole is less than the negative region feet subterranean level. Then the right choice is D.

Jazmyn uses 2 gallons of paint to paint 5 walls. He uses 4 gallons of paint to paint 10 walls. How many gallons of paint does he use per wall?
Answer:
2/5 gallons
Step-by-step explanation:
If it takes 2 gallons of paint to paint 5 walls, then the amount of gallons used per wall can be calculated by comparison
[tex]5 walls = 2 gallons \\ 1 \: wall = x \: gallons \\ by \: cross \: multiplication \\ 5 \times x = 2 \times 1 \\ 5x = 2 \\ x = \frac{2}{5} [/tex]
Hence, 2/5 gallons of paint is used per wall.
Solve: 14+(5x-7)=19+3x
The answer is x=6, have a good day!
Answer:
[tex]x=6[/tex]
Step-by-step explanation:
First let's put our equation
[tex]14+(5x-7)=19+3x[/tex]
Let's drop our parenthesis[tex]14+5x-7=19+3x[/tex]
Subtract 3x from both sides[tex]14+2x-7=19[/tex]
Simplify[tex]7+2x=19[/tex]
Subtract 7 from both sides[tex]2x=12[/tex]
Divide both sides by 2[tex]x=6[/tex]
