Write  -1 1/3  as a common fraction: -4/3

-4/5 x -4/3  =  16/15

A negative times a negative is positive; multiply the numerator times the numerator and the denominator times the denominator. 

First you have to get to know her better befriend her then you need to have things in common. Remember her birthday and what she likes. If she doesn't smile when you walk in she probably just wants to be friends. 

2x + 9 + 3x - 1  =  x + 12

Simplify the left side:

5x + 8  =  x + 12

Get all the x-terms to one side; subtract x from both sides:

5x - x + 8  = x - x + 12

     4x + 8  =  12

           4x  =  4

             x  =  1

However, if you mean that 3/7ths of the loan was $2800, then the way to solve it is:

         (3/7)(loan) = 2800

multiply both sides times 7/3:

         (7/3)(3/7)(loan) = (7/3)(2800)

                         loan  =  7/3 x 2800

To solve:  1/2*X*X = X,

I will write it as:  1/2X² = X

To get rid of fractions, I would multiply both sides by 2:

                                            2(1/2X²) = 2(X)

which becomes:                            X² = 2X

I would subtract 2X from both sides to get all the X-terms to one side:

                                               X² - 2X = 2X - 2X

                                               X² - 2X = 0

Factor:                                   X(X - 2) = 0

So, either      X = 0      or     X - 2 = 0  --->  X = 2

you can show 199 you can really you should copy off of mine ok ok ok ok ok yeh

What do you mean by solving it?

Do you mean:

how to graph it?

how to find a value for f(x), when you know x?

how to find the value for x that will make f(x) = 0?

how to find its inverse?

If the total tuition is $2800.00 and the loan was for 3/7 of the total tuition,

you can translate "3/7 of the total tuition" into math this way:  'of' becomes 'times' and 'the total tuition' is $2800:   3/7 x $2800.  Use the calculator to multiply 3/7 times 2800.

Or, am I completely misunderstanding you?

The answer is 4, that was a tough question

Isn't tau (τ) the same as 2π?

So, when you want to use τ, enter (2π).

Are you asking that: if tuition was $2800.00 and you received a loan for 3/7ths of the tuition, how much is the loan?

If so, multiply 3/7 times 2800:  (3/7) x $2800 =  the answer.

You can use the calculator at this site to obtain the answer.

the answer is 7/6

The mean is calculated by adding all the individual wages and then dividing by the number of persons.

The mean can be influenced by a few very large, or very small numbers.

If you employ 8 persons, and their salaries are:

$80,000.00

$72,000.00

$20,000.00

$20,000.00

$20,000.00

$20,000.00

$20,000.00

$20,000.00

To find the mean, add them together (you will get $272,000) and you divide by the number of employees (8), you will get a mean salary of ($272,000 ÷ 8) $34,000.00; quite a bit more than wnat most of the employees earn. Two of the employees earn more than the mean wage; six earn less.

in a square root you times the number by itself, therefor 1*1=1.

yes 48/12=4

1/3 = 0.333333...                    1/6 = 0.16666666...

2/3 = 0.666666...                    5/6 = 0.8333333...

If you get something like                 0.142857142857...

you can use this procedure:

first, set the decimal to n:  n  =   0.142857142857...

then, figure out what you have to multiply by to move the whole group of decimals one cycle the part that's repeated) over; in this case, since the cycle consists of 6 digits, multiply by 10^6 = 1 000 000:

                1 000 000n  = 142857.142857...

                                n  =           0.142857... 

subtract:    999 999n  =  142857

                                n  =  142 857 / 999 999

reduce:                   n   =  1 / 7                (This is a harder example then what you'll probably get.)

It depends..... Message me and i will let you know! :P

taht not helping

Km, kilometers, is a measure of length; this cannot be directed converted to square meters.

Is there something else to this problem?

1)  To find adjusted gross inome, add what he earned in wages and the amount of interest that he earned.

2)  To find his taxable income , subtract the standard deduction for a single person from his adjusted gross income that you found in step 1.

3)  The amount of tax cannot be calculated from the information given; you will need to look this up in a tax table, or calculate a percentage, depending upon the information that you are given.

4)  The size of the refund is found by subtracting the amount of tax owed from the amount that his employer withheld.

If you draw a point where they started, a point where the one moving north is, and a point where the one moving east is, these three points will form a triangle with a right angle at the point where they started.

You can use the Pythagorean Theorem to calculator their distance apart. One leg is 20, another leg is 15 and the hypotenuse is the unknown distance.

Pythagorean Theorem:  c²  =  a² + b²

where c is the length of the hypotenuse (the unknown) and a and b are the known legs:

 c²  =  a² + b²   --->    c²  =  20² + 15²   --->    c²  =  400 + 225   --->    c²  =  625   --->  c  =  √625  

     --->   c  =  25

Gross pay:  30 x $8.00 = $240.00

Subtract:

-- federal income tax = $22.00

--state income tax = $7.15

--FICA (6.20% of $240.00) = $14.88

--Medicare tax (1.45% of $240.00) = $3.48

Final amount:  $240.00 - $22.00 - $7.15 - $14.8 - $3.48  =  $192.49

$1000.00 is invested.

2% of $1000.00 is deducted:  $20.00 is deducted; leaving $980.00

12.45% increase of $980.00 is $122.01; at the end of the year, the value is: $1102.01.

Next year: 2% ($22.04) is deducted; leaving $1079.97.

12.45% increase ($134.46) is added; at the end of the year, the value is: $1214.43.

Can you take this forward one more year?
