Hi there!

<em><u>Answer:</u></em>

<em><u>=2x</u></em>

<em><u>*The answer must have  a positive sign.*</u></em>

Step-by-step explanation:

<h2><em><u>Lesson: Using Properties to Simplify Expressions</u></em></h2>

First, you add/subtract by the numbers from left to right.

3x-x=2x

Then you use group like terms to change sides.

2x+12-12

Simplify and solve.

12-12=0

Final answer is 2x

I hope this helps you!

Have a nice day! :)

You need to combine like terms. So...

12 + 3x - x - 12 = 2x

1.
a. your answer is correct
b. 60 and  hndreths=60.08
c. 16 and 8 thousanths=16.008
d. 60 and 8 tenths=60.8
e. your answer is correct
f.  your answer is correct

2.  16.207, 6.9, 16.19, 16.26
so the greatest is obviously one of the 16's
compare
16.207, 16.190, 16.260
obviously, the order is 16.260,16.207,16.190
then the last one is 6.9 so the order is 16.26,16.207, 16.19, 6.9 and the numbers in order is 2,4,3,1

3. I can't see the puzzle that well, but 11.88 is more than 11.50 since 0.88 is more than 0.50


4.  can't see the puzzle that mmuch
hundreths is 0.0x x is the hundrreths since exg 1/100=1 hundreths=0.01


5. remember if the number is more than five round up and if less than 4 round down so
10.5, 10.6, 10.7 10.8 10.9 10.1 10.2 10.3 10.4 would work

6. tenth=0.8 so the numbers could be 17.81, 17.82 17,83

7.rembmber the decimal places and line them up so again
6.081, 6.082 6.083 and so on



8. 1/2=0.5 or 0.50000

9. the greatest decimal
first find the greatest whole number
60
then find all the 60's and read from left to right the numbers after the decimal, the biggest number to the left is bigger, if they are the same, move one place to the right and count again


10.  I can't seee the puzzzle very clearly but hte answer is pirates

<u>Since half of the numbers are even, 2, 4, 6</u>

  • P(even) = 3/6 = 1/2

#2

<u>Multiple of 3 are 3 and 6:</u>

  • P(multiple of 3) = 2/6 = 1/3

#3

<u>The numbers ≤ 4 are: 1, 2, 3, 4</u>

  • P(≤4) = 4/6 = 2/3

#4

<u>Prime numbers are 2, 3, 5</u>

  • P(prime) = 3/6 = 1/2

#5

<u>Numbers > 1 are 2, 3, 4, 5, 6</u>

  • P(>1) = 5/6
