The system can't have only zeros .
It will be only one answer or there will be no answer.
Hence one variable at least not equal to zero for proper system.

PLEASE ANSWER WITH SOLUTION PLS

katen-ka-za [31]

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway? well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Find YW. YW = _<br><br> I just need the answer for YW no explanation needed.

KATRIN_1 [288]

Answer:

$YW=20\ units$

Step-by-step explanation:

we know that

In a parallelogram the diagonals bisect each other

The figure XYZW is a parallelogram

VW=VY

VX=VZ

<em>Find the value of b</em>

VW=VY

substitute the given values

$b+8=5b$

solve for b

$5b-b=8\\4b=8\\b=2$

Find the length of YW

$YW=YV+VW$ ----> by addition segment postulate

$YW=5b+b+8$

substitute the value of b

$YW=6(2)+8=20\ units$

Can someone help me with this?

faltersainse [42]

Hello, the answer should be A,B and D options.

First, let's edit the given equations option-by-option.

<h2>Option A:</h2>

$-5x+12=5x+12$

$-5x-5x=-12+12$

$-10x=0$

$x=0$

There is only one solution which is $x=0$ .

<h2>Option B:</h2>

$-5x+12=5x-5$

$-5x-5x=-12-5$

$-10x=-17$

$x=\frac{17}{10}$

There is only one solution which is $x=\frac{17}{10}$ .

<h2>Option C:</h2>

$-5x+12=-5x-12$

$-5x+5x=-12-12$

$0\neq -24$

In Math, zero is <u>not equal to</u> minus twenty four ( $0\neq -24$ ) that's why we do not have any solution in this equation.

<h2>Option D:</h2>

$-5x+12=-12x-12$

$-5x+12x=-12-12$

$7x=-24$

$x=-(\frac{24}{7} )$

There is only one solution which is $x=-(\frac{24}{7} )$
