If 2x² – 2y = 125 and x - y = 2.5, find the value of<br> x + y
uysha [10]

We can solve this using substitution.

because x-y=2.5

x=y+2.5

Now substitute x into other equation.

2(y+2.5)^2-2y=125

2y^2+10y+12.5-2y=125

2y^2+8y-112.5=0

Now comes the ugly part

y=-4+-sqrt(16+900)

y=-4+-sqrt916

y=-4+-2sqrt229

x=-1.5+-2sqrt229

What is 22.5% written as a fraction in simplest form?​
murzikaleks [220]

Answer:

9/40

Step-by-step explanation:

  • Write down the percent divided by 100 like this:

22.5/100

  • Multiply both top and bottom by 10 for every number after the decimal point:
  • As we have 1 digit after the decimal point, we multiply both numerator and denominator by 10, or, simply shift 1 decimal place to the right. So,

(22.5*10)(100*10)= 225/1000

  • Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(225,1000) = 25.

225 ÷ 25/ 1000÷25 = 9/40

What is the answer for 2,4,6.....please show work and need answer asap.....thank you
sashaice [31]
You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them.  Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.

The formula is:

             Volume  =  (length)  times  (width)  times  (height) .

With that formula, you can directly solve problems #1, #2, #3,
#4, and #8.  It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.


For #6, start with the same formula:

                                     Volume = (length) x (width) x (height)

Divide each side by
(width) x (height), and
then it says:               Length = (volume) / (width x height) .

#6 gives you the volume, width and height. 
 You can just write them into this equation,
and bada-bing, you'll have the missing length.
