-5y=9x +2x -2x
-5y=9x
X= -5y/9
This is the best I got Require to make 2 equations with the same repeating part and subtract them to eliminate the repeating part.
begin by letting x = 0.5555555................. (1)
To obtain the same repeating part after the decimal point need to multiply by 10
hence 10x = 5.555555........................(2)
It is important to obtain 2 equations in x, where the recurring part after the decimal points are exactly the same.
now subtract (1) from (2) to obtain fraction
(2) - (1) : <span>9x=5⇒x=<span><span>59</span></span></span>
Answer:
Can you please provide a problem
The value of x is the final solution you get in your problem
Step-by-step explanation:
For example
10x = 50
X = 50/10
X = 5
The value of x is 5
Answer:
r = 3sqrt*2
Step-by-step explanation:
We'll need the formula for the circumference of a circle: C = 2*pi*r
This can be solved for r:
C
r = -----------
2*pi
Here, with C = 6sqrt(2)*pi,
6sqrt(2)*pi
r = ------------------ = 3sqrt*2
2*pi
Answer:
r=2.808cm h = 100cm
then we get volume of cylinder that is 2744 As explained below
Step-by-step explanation:
Volume of cylinder = πr²h
Surface area of cylinder = 2πrh +πr² (1)
h= 2744 /πr²
put value oh h in equation (1)
Area =[2πr] 2744 /πr²
=[5488/r +πr²]
dA/dx=0
i.e 2πr=5488/r²
Solving this r.r= ∛5488/2π
=2.808
taking second derivation we get 100
