Answer:

We end up with our original number

Step-by-step explanation:

Let x be our number

We increase by 100

increase = old number * 100%

increase = x*1

increase = x

New number = old number + increase

= x+x

=2x

Now we decrease by 50%

decrease = number *50%

= 2x*.5

Final number = new number - decrease

= 2x-x

Determine the equation of the joint value

slega [8]

$\bf \qquad \textit{direct proportional variation}\\\\
\begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
\\
&& y={{ k }}x
\end{array}\\\\
-----------------------------\\\\$

$\bf \textit{x varies directly with y and z}\implies x=\underline{k}yz\qquad \underline{k}=
\begin{array}{llll}
constant\ of\\
variation
\end{array}
\\\\\\
\textit{we also know that }
\begin{cases}
x=120\\
y=5\\
z=8
\end{cases}\implies 120=k(5)(8)\implies \cfrac{120}{5\cdot 8}=k
\\\\\\
\boxed{3=k}\qquad thus\implies x=\underline{3}yz
\\\\\\
\textit{now what's "x" when }
\begin{cases}
y=6\\
z=2
\end{cases}\implies x=3(6)(2)$

What remainder does the number (−50) leave after division by 7?

m_a_m_a [10]

This is a tricky question, all you need to know is that the remainder cannot be a negative number.

So, -50 mod 7 = 6, since -50 /7 = 8 with remainder of 6

When Kirk and Elisa formed their general partnership, Kirk contributed 90 percent of the capital, and Elisa contributed 10 perce

topjm [15]

Answer:

Her share is $3500

Step-by-step explanation:

As a general rule, if they did not make any specifications on how they would share the profit, then they should share it according on how percentage of capital they contributed. Since Elisa only contributed 10%, then she should get only 10% of profit, as a result, her share is 35000*0.1 = $3500.
