1-4x/2x+1=4/1-5x
solve in quadratic equations​

Answers

Answer:

I can only assume that the entire 1-4x is divided by 2x, and 4 by all of 1 - 5x.  You can guarantee more accurate results by using brackets where appropriate.  If I read that expression with the correct notation, it reads as [tex]1 - \frac{4x}{2x} + 1 = \frac{4}{1} - 5x[/tex].

Assuming instead that it's meant as [tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}[/tex], we can solve it as shown below, giving us x values of 1 and 3/20 (or 0.15).

Step-by-step explanation:

First let's reformat this to the usual ax² + bx + c format:

[tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}\\(1 - 4x)(1 - 5x) = 4(2x + 1)\\1 - 5x - 4x + 20x^2 = 8x + 4\\20x^2 - 5x - 4x - 8x + 1 - 4 = 0\\20x^2 - 17x - 3 = 0[/tex]

Let's solve it with the quadratic formula:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\\\\x = \frac{17 \pm \sqrt{-17^2 - 4\times 20 \times( -3)} }{2\times20}\\\\x = \frac{17 \pm \sqrt{289 + 240} }{40}\\\\x = \frac{17 \pm 23 }{40}\\\\x = 1, \frac{3}{20}[/tex]

8. Syairra needs to take an Uber to get to
the airport. The Uber charges $5.00 for
the first mile, and then $3.00 for each mile
after that. If the total charge is $62.00,
then how far was Syairra's taxi ride to the
airport?

Answers

you would do “62=3x+5”

subtract 5 from both sides to get 57=3x
divide both sides by 3 to get 19.

the answer is 19 miles

Answer: 20 miles

Step-by-step explanation:

Since the Uber charges $5.00 for the first mile you have to subtract that from the total which is 62.

62.00 - 5.00 = 57.00

Then you keep subtracting 3.00 from 57.00 or you can divide 57 by 3 because 57 is how much money is left and the Uber charges 3 dollars for each mile after the first.

57.00 divided by 3.00 is 19

Then add 1 to 19 which equals 20 miles. You add 1 to 19 because 19 is the amount of miles she goes but that doesn’t include the 1st mile.
