2x+6=7x-14

6 + 14 =7x - 2x

20 =5x divide both sides by 5

x =20/5

x = 4

i asked this question -160%+0.1+25% and got a wrong answer it was -1.99875 the correct answer was -1.25 piz fix

-160%+0.1+25% =

-160/100 + 0.1 + 25/100 =

-1.6 + 0.1 + 0.25 =

-1.5 + 0.25 = -1.25

because no matter what happens in life your surroundings shape you into who you are.

It doesn't mean anything the way you have written!.

4x-3=2x+7 

4x - 2x =7 + 3

2x = 10 divide both sides by 2

x = 10/2

x = 5

Put simply,a combination is just a collection of objects and  permutations are different ways of arranging that combination.To show this ---

I can have a combination of 4 people on a commitee,say Art, Bert,Chas and Dave.

I could have picked this same commitee in 24 different ways ( that is 24 permutations)

To show a few,so you get the idea,I could have picked

Art,Chas,Bert,Dave or

Art,Chas,Dave,Bert or

Chas,Dave,Bert,Art     (I'm not listing all 24 of them!)      ,all of which gives me the same combination,but just permuted in different ways.

If I have a combination of 4 objects,the number of permutations of that combination is 24. Why?

-the number of choices I have for my first pick is   4.  Now I only have  3 choices left for my next pick,and at this stage ,with every one of my 4 picks,I have a choice of 3 picks  ie  4 x 3. After my 3rd pick,I only have 2 choices left, so now I have 4x3x2 permutations and finally only one left, we usually include the 1   to write 4x3x2x1.

On the top left side of the calculator, there is a button labeled '2nd', press this and the normal buttons should be replaced. Note that having an 'a' before the function represents the inverse in this case. For instance, 

asin(x) = sin^-1(x)

and so forth for cos, tan and any other trig function. 

9 + 10 = 19

i^1 = i

i^2 = -1

i^3 = -i

i^4 = 1

i^5 = i and then the pattern repeats on and on......etc.

Actually should have been written as -(1+16/100)=-1 4/25

If there are six apples, and two people to split the apples evenly across so both get an equal amount of apples, then:

\(n=\frac{a}{p}\)

Where n is the number of apples each person gets, a is the total amount of apples, and p is the total amount of people. 

Substituting the numbers in gives:

\(n=\frac{6}{2} = 3\)

n is equal to three, so each person should receive three apples each. 

The number π is a mathematical constant, the ratio of a circle's circumference to its diameter, commonly approximated as 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes spelled out as "pi" (/paɪ/).

Infinity plus infinity is equal to infinity; this is due to the nature of infinity as a mathematical concept.

(18*x^6)*y^12 =18 x^6 y^12

if 2 dogs is 89 pounds and one is 34 how much is the other one

89 - 34 =55 pounds - the weight of the other dog.

The same as you use "positive cosine"!!

What is -1.16 as a fraction

-1 + 16/100 = -1 4/25

what is 9 squared plus b squared equals 41 squared

9^2 + b^2 = 41^2 subtract 9^2 from both sides,

b^2 = 41^2 - 9^2

b^2 =1,681 - 81

b^2 =1,600 Take the square root of both sides,

b =40

What is 40% of 31590???

40/100 x 31,590 =12,636
