That was today at about 8 o'clock {nl} by heureka and me.

wie rechne ich mit x ungleich 0,5
Ist die Variable x in einem Term oder einer Gleichung enthalten, darf x jeden Wert, natürlich, reell, komplex, irrational, transzendent, positiv, negativ und so weiter, annehmen,
nur nicht den Wert 0,5. !
The length of a rectangular garden is double it's width. The area of the garden is 162 m squared. If the garden wishes to construct a fence diagonally across the garden, how much fencing(in meters) will be required? round your answer to the nearest meter
\(A=l\times w= 2w\times w =162\ m^2\)
\(2w^2=162m^2\)
\(w=\sqrt \frac{162\ m^2}{2} = 9m\)
\(l=2w=2\times 9m = 18m\)
\(f = \sqrt {w^{2}+l^2}\) = \(\sqrt{(9m)^2+(18m)^2}\)
\(f=\sqrt{405m^2}\) = \(20.125\ m\)
\({\color{blue}21\ m \ fencing \ will \ be \ required.}\)

17/20>3/5=
\({\color{blue}\frac{17}{20}> \frac{3}{5} = 0.85>0.6 \ \ and \ that \ is \ correct.}\)

What is 100 5/8 divided by 14 3/8
\(100\frac{5}{8}: 14\frac{3}{8}\) = \(\frac{805}{8}: \frac{115}{8}\)
= \(\frac{805}{8}\times \frac{8}{115}\) = \(\frac{805}{115}\)
= 7 !
how do you change this equation (5x+4y+8) into an equation that I can use for slopes?
There is no equation.
5 5/12times 3 1/3
\(5\frac{5}{12}\times3\frac{1}{3}\)= \(\frac{65}{12}\times\frac{10}{3}\) = \(\frac{650}{36}\) = \({\color{blue}18\frac{1}{18}}\)
m=((x+nx+4)/2) solve for x
\(m=\frac{x+nx+4}{2}\)
\(2m=x+nx+4\)
\(2m-4= x\times(n+1)\)
\({\color{blue}x= \frac{2m-4}{n+1}}\)
What is 2/3 × 3/7
\({\color{blue}\frac{2}{3}\times\frac{3}{7}=\frac{2\times3}{3\times7}=\frac{2}{7}}\) !
