Express 763636363636 as a rational number

shtirl [24]

$x=0.7636363\ldots$
$10x=7.636363\ldots$
$1000x=763.636363\ldots$

$\implies1000x-10x=990x=756\implies x=\dfrac{756}{990}=\dfrac{42}{55}$

Solve using the method of elimination and determine if the system has 1 solution, no solutions, or infinite solutions

Minchanka [31]

$\begin{array}{rrrrr} 10x&-&18y&=&2\\ -5x&+&9y&=&-1 \end{array}~\hfill \implies ~\hfill \stackrel{\textit{second equation }\times 2}{ \begin{array}{rrrrr} 10x&-&18y&=&2\\ 2(-5x&+&9y&)=&2(-1) \end{array}} \\\\[-0.35em] ~\dotfill\\\\ \begin{array}{rrrrr} 10x&-&18y&=&2\\ -10x&+&18y&=&-2\\\cline{1-5} 0&+&0&=&0 \end{array}\qquad \impliedby \textit{another way of saying \underline{infinite solutions}}$

if we were to solve both equations for "y", we'd get

$10x-18y=2\implies 10x-2=18y\implies \cfrac{10x-2}{18}=y\implies \cfrac{5}{9}x-\cfrac{1}{9}=y \\\\\\ -5x+9y=-1\implies 9y=5x-1\implies y=\cfrac{5x-1}{9}\implies y = \cfrac{5}{9}x-\cfrac{1}{9}$

notice, the 1st equation is really the 2nd in disguise, since both lines are just pancaked on top of each other, every point in the lines is a solution or an intersection, and since both go to infinity, well, there you have it.

John and Liz are sharing a large pizza. John ate of the pizza, and Liz ate of the pizza. How much of the pizza is left?

Aloiza [94]

Add what they ate
2/3 + 1/4 =
11/12
Then subtract that from the whole pizza
12/12 - 11/12 =
1/12
1/12 of the pizza is left
