Answer:

Step-by-step explanation:
We want to simplify:

We convert to improper fraction to get:

We now deal with the parenthesis by multiplying with the reciprocal of 2.

This gives:

We multiply to get:

This simplfies to:

We write as mixed number

First I would distribute the left part like so:
12x - 18 - (5x + 7)
Then I would distribute the right side like so: (I'm just distributing a negative sign)
12x - 18 - 5x - 7
Then I combine like terms like so: (12x and -5x)
7x - 18 - 7
Then I would combine the other like terms like so: (-18 and -7)
7x - 25
I hope that helps! Feel free to let me know if you have any questions! :3

Answer:
line up the decimal points first and then compare values, starting with the ones places, then compare the tenths place, then the hundredths, etc.
0.210 - this is 21/100
1.320 - this is 1 32/100
2.100 - this is 2 1/10
0.021 - this is 21/1000
Step-by-step explanation:
smallest is 0.021
0.210
1.32
largest is 2.1

Step-by-step explanation:</h3>
Add the two equations.
... (-4x) + (y) = (y +3) +(-4x -3)
Add 4x -y to both sides.
... -4x +y +4x -y = -4x +y +4x -y
... 0 = 0 . . . . . true for all values of x (or y)
Both equations describe the same line.

The graph shows the first equation as a red line. The second equation is shown using a "blue dot" texture, so you can see it overlays the red line.
