8x + 2 – 6 = 4x +8 +3x

Mathematics
1 answer:
Viefleur [7K]3 years ago

The first step is to combine like terms. So u would do 2-6. You then get -4 then u just bring everything else down. So now u should have this :

8x -4 = 4x + 8 + 3x

Now you do the same thing to the other side. U combine like terms which in this case are 4x and 3x. So u just do 4+3 which is 7 so now u have 7x. So now ur equation would be:

8x -4 = 7x +8

Now u do the inverse of 7 which would be -7 and u do that on both sides. So it would look like this :

8x -4 = 7x + 8
-7x. -7x

So now 7 and -7 cancel each other other and 8 -7 is 1 so now u have one x. So ur equation would now look like this:

1x -4 = 8

Now u do the inverse of negative 4 which is +4. So you would add 4 on both sides on both sides. Like shown:

1x -4 = 8
+4 +4

So u just add 8 + 4 which is 12. Now since anything times 1 is itself ur answer will be X=12


Hope this helped

Decimal And fraction in meters of 8 centimeters
netineya [11]
Ok so
Knowing that 1 metre consists of 100cm,
You can conclude and agree that 8 cm is 8/100, correct?
Now, when converting fractions to decimals, it makes it easier out of 100 or 10. Since it's out of 100 already, you take the amount of zero's in 100 (two) and you move the decimal point (2) places to the <em /><u>left<em /></u> 

This gives you 0.08
So the fraction is 8/100, which then can be simplified to 4/50, then to 2/25
and the decimal is 0.08.

I NEED HELP PLS!!!!
hram777 [196]

Answer:

15

Step-by-step explanation:

For these kind of problems, its best to use a Venn Diagram.

Lets break down the information:

<em>There are 50 students total.</em>

<em>25 take Math competiton classes.</em>

<em>29 take Geometry</em>

<em>12 take history and </em><em><u>no math classes</u></em>

<em>19 take </em><em><u>both math classes</u></em>

Now, make a Venn Diagram.

[Look at the photo attached. Also, the blank spaces in the Venn Diagram are ones that no student takes.]

The 12 taking history and no math classes and 3 kids not taking any of those classes look like they're the only ones not taking either math class.

12 + 3 = 15.

So the answer is 15.

[I'm not sure if this is correct or if I made a mistake so please let me know! Thank you! I hope this helps!]

A conductor needs 5 cellists and 5 violinists to play at a diplomatic event. to do this, he ranks the orchestra's 10 cellists an
DaniilM [7]
Ranking is very critical in this problem. Therefore, the most applicable mathematical theory is permutations.

Ranking possible for the cellists:
Needed cellists = 5
Total available cellists = 10
Possible number of rankings = 10P5 = 10!/(10-5)! = 30240

Ranking possible for the violinists:
Needed violinists = 5
Total available = 16
Possible number of rankings = 16P5 = 16!/(16-5)! = 524160

Therefore,
Ratio of rankings (cellists to violinists) = 30240/524160 = 3/52

PLS ANSWER QUICK I WILL GIVE BRAINLIEST
NISA [10]

Answer:

B

Step-by-step explanation:

First, we are decreasing the number so it has to be a decrease.

Next, we divide 7/31 and get around 0.23, which also represents 23 percent.

This only shows that 7 is 23 percent of 31, so we need to find the decrease by seeing the difference of 100 and 23.

We get 100 - 23 = 77, and because it is a decrease we get B.
