PLEASE ANSWER ASAP! MUST BE CORRECT! MORE POINTS GIVEN!!! Sally said that when you add or subtract positive or negative decimals, you can change the order of the decimals and still get the same answer.
Use these decimals to answer the questions:
–6.2, 5.71, –3.96, 2.84

Write a rule about changing the order of the numbers in adding and in subtracting positive and negative decimals.

Answers

These are the two rules for when a and b are positive numbers.
a + b = b + a
a - b ≠ b -a
a - b = -b + a

For example:

5.71 + 2.84 = 2.84 + 5.71
8.55 = 8.55

5.71 - 2.84 ≠ 2.84 - 5.71
2.87 ≠ -2.87

5.71 - 2.84 = -2.84 + 5.71
2.87 = 2.87

These are the rules for when a and b are negative numbers.
a + b = b + a
a - b = b + a

For example,

-6.2 + (-3.96) = -3.96 + (-6.2)
-6.2 - 3.96 = -3.96 - 6.2
-10.16 = -10.16

-6.2 - (3.96) = -3.96 + (-6.2)
-10.16 = -10.16

Also, if a is a positive number, while b is a negative number, we see these rules:
a + b = a - b
a - b = a + b

For example,

5.71 + (-6.2) = 5.71 - 6.2
-0.49 = -0.49

5.71 - (-6.2) = 5.71 + 6.2
11.91 = 11.91

Also, if a is a negative number while b is a positive number, then these rules will apply:
a + b = b - a
a - b = -b - a

For example,

-3.96 + 2.84 = 2.84 - 3.96
-1.12 = -1.12

-3.96 - 2.84 = -2.84 - 3.96
-6.8 = -6.8

I hope this helps! :)

According to the school survey 12% of the students at Rockwood high school speak Spanish there are 36 students at the school who speak Spanish how many students were surveyed

Answers

The percentage is that indicating the hundredth total number of students surveyed such that 12% of them are 36 will be 300.

What is the percentage?

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

Let's suppose the total number of students that are surveyed was x.

It is known that x% of y is given as, (x/100)y.

Therefore,12% of x is (12/100)x = 0.12x

The 12% of the total students is 36.

So, 0.12x = 36

x = 36/0.12 = 300

Hence "The percentage is that indicating the hundredth total number of students surveyed such that 12% of them are 36 will be 300".

80% of how many games is 32 games?

Answers

percent means parts out of 100 so
80%=80/100=8/10=0.8
'of' can be translated to as multiply
0.8 times x games is 32 games
0.8 times x=32
note:0.8x= 0.8 times x
0.8x=32
multiply both sides by 10
8x=320
divide both sides by 8
x=40
the number is 40

So, you can set it up like: is over of = % over 100
We need a proportion to solve that answer.
So put the "is" part, which is 32 on top on the left over the "of" part, which is what you do not know, so put x as a variable. Now put 80% since it's the percentage over 100 on the right side. Now, it should look like this: 32/x=80/100(you do not need to include the % sign). Now cross multiply and you get: 80x=3200. Now divide 80 on both sides and you get 40. So there would be 40 games.
Hope this helps. :-)
PS I'm sure glad I learned about proportions to help. (I hope I did)
