HELP PLEASE FOR 35 POINTS!!!! Solve the rational equation 3 divided by x equals quantity 4 times x plus 3 divided by x squared,

denis23 [38]

Answer:

$x=-3$

Step-by-step explanation:

So, we are given:

$\frac{3}{x}=\frac{4x+3}{x^2}$

First, we should immediately rule out 0 as an answer. This is because the if $x=0$ , the equation would be undefined.

$x\neq 0$

Now, cross multiply.

$3(x^2)=x(4x+3)$

$3x^2=4x^2+3x$

Divide everything by x (and we can do this safely because we already know x cannot be equal to zero).

$3x=4x+3$

$-x=3$

$x=-3$

We didn't run into any possibilities for extraneous solutions.

han want to buy a $30 ticket to a game, but the pre-oder tickets are sold out, he knowns there will be more tickets sold the day

Kay [80]

Answer: $\$90$

Step-by-step explanation:

Given

The price of the ticket prior to match day is $\$30$

It is stated that there is $200\%$ the markup on match day i.e.

The selling price of the ticket is

$\Rightarrow S.P.=30+30\times 200\%\\\Rightarrow S.P.=30+30\times 2=30+60\\\Rightarrow S.P.=\$90$

So, han must expect to pay $\$90$ on that day

Can you simplify -3.2/0.8

Vlad1618 [11]

<h3>Answer: -4</h3>

Explanation:

Move the decimal point to the right one spot for each value

-3.2 turns into -32

0.8 turns into 8.0 which is the same as 8

That means the given fraction is the same as -32/8 which simplifies into -4
