How do you change a fraction to a decimal?

Answers

To change a fraction into a decimal, divide the numerator by denominator. This gets you a decimal. Example.
4/25 Oh OK! 4 divided by 25 equals.... 0.16! GG

:)-Kibeye

To convert a Fraction to a Decimal manually,
follow these steps:Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.Step 2: Multiply both top and bottom by that number.Step 3. Then write down just the top number, putting the decimal point in the correct spot (one space from the right hand side for every zero in the bottom number)

Find the solution 2x+5y=12

Answers

You can draw a graph of that equation. When you do that, the graph is a
straight line, and EVERY POINT on the line is a solution of the equation.
There are an infinite number of them.

You can find as many of them as you want. Pick any number you like
out of the air, and call it 'x'. Now find the number that's 2.4 more than
negative 0.4 of 'x' and that's 'y'. Together they form one solution to
the equation.

can anyone help me on these problems and explain how you did it please

Thank you
PLEASE HELP

Answers

a. $2 x^(2) -5x-3=2 x^(2) -6x+x-3$ (I'll explain how I split it in a bit)
$=2x(x-3)+1(x-3)$   Look for common factors between the 1st two and then the second two while trying to make sure the variables in the brackets are the same.
Now you only have to write the value in the bracket once and then join the outer factors in their own bracket so your final answer will be $(2 x^(2) +1)(x-3)$

For the first thing I did, I multiplied the first part of the equation by the last part= 2 $x^(2)$ x -3=-6 $x^(2)$ . I then proceeded to find two numbers that can be multiplied to give the result and when added will give the middle part (-5x).
Factors of -6 $x^(2)$ are: -1x and 6x, -2x and 3x, -3x and 2x, -6x and 1x. The only ones that add up -5x are -x and 6x so that was why I used them.

b. 3x-2/2x^2-5x-3 - 1/x-3
$(3x-2)/(2 x^(2) -5x-3)- (1)/(x-3) = (3x-2)/((2x+1)(x-3)) - (1)/(x-3)$
$= (1(3x-2) +1(2x+1))/((2x+1)(x-3))$
   $= (3x+2x-2+1)/((2x+1)(x-3) )$
  = $(x-1)/(2 x^(2) -5x-3)$
