4/9x - 1/9 is an expression, not an equation. An expression cannot be solved.
Well if it's the hardest way to solve this decimals. I use this tricky way to get the decimal number. i used the convert fraction; for ex: the fraction of 8/12. you have to divide 8 by 12 like this: 8 ÷12 = 0.6666666666 * USE YOUR CALCULATOR TO SOLVE THIS * so the decimal form of 8/12 is 0.6666666 . ---------------- Hope that helps, Mrs. Yung.
57 is an integer and so there is no sensible way to represent it as a proper fraction.
153 is an integer and so there is no sensible way of writing it as a fraction or mixed number.
To find out what (2.777) and so on is as a fraction, we can first separate the 2 and the 0.777... out to make 2 + 0.777.Now, we must find out what 0.777 is as a fraction. Let's call it x. Therefore, x = 0.777.This means that 10x = 7.777. We can subtract 10x to x, which is 9x. Thus, 9x = 7.777 - 0.777 = 7. We can now divide both sides by 9 to get x = 7/9. Now we can simply add 2 and 7/9 together, which gives us 25/9.
120/6 is an integer, not a fraction so there is no sensible way to represent is as a mixed fraction.
x - 10x = 9x, so 9x + 3 = 0, so 9x = -3 so x = -1/3
0.09 = 9/100 so 0.09x = 9x/100
9x4= 36 36x25180= 906480 so therefore your answer is 906,480
Presumably you mean 0.1 recurring..... if x=0.11111111..... 10x=1.11111111..... so 10x-x=9x=1 9x=1 so x=1/9
There is no need to do so.
multiply the nos., 2(9), the answer is 18. then, multiply the variables, x(x), the answer is x2 so the answer is: 18x2
Let the numerator be x, so the denominator is x + 4. So we have:x/(x + 4) = 9/15 (cross multiply)15x = 9(x + 4)15x = 9x + 3615x - 9x = 9x - 9x + 366x = 366x/6 = 36/6x = 6x + 4 = 6 + 4 = 10Sine the numerator is 6 and the denominator is 10, then the fraction is 6/10, which in the simplest form is equal to 3/5.Since 9/15 in the simplest form is also equal to 3/5, then 6/10 is equivalent to 9/15.Thus, 6/10 is the required fraction.
-9x + 2y = -69 So 2y = 9x - 69 The other equation can be written as 6x - 4y = 54 or 6x - 2*2y = 54 Substituting for 2y gives 6x - 2*(9x - 69) = 54 6x - 18x + 138 = 54 12x = 84 x = 7 and then 2y = 9x - 69 = 9*7 - 69 = 63-69 = -6 so that y = -3
(the fraction bar means divide) so you just do 6 divided by 1 =6
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
9x+3y=-68 -2x+y=18 We are asked to solve with substitution so we first write y=18+2x. Let us substitute this into the first equation. 9x+3(18+2x)=-68 9x+54+6x=-68 15x=-68-54=-122 so x=-122/15 and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15 So the solution is (-122/15,26/15) which is an ordered pair.
