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]

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches. He also uses 333.06 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

The amount of fabric was used on :

a) headband for each player = 15.88 inches of fabric

b) wristband for each player = 8.54 inches of fabric

Step-by-step explanation:

From the above question, we were told:

For headbands

Carl is making accessories for the soccer team. He uses 666.96 inches of fabric on headbands for 39 players and 3 coaches.

Total number of persons = 39 players + 3 coaches = 42 persons

42 persons = 666.96 inches

1 person = x

Cross Y

42x = 666.96 inches

x = 666.96 inches/42

x = 15.88 inches

For wristbands

He also uses 333.06 inches of fabric on wristbands for just the players.

We have 39 players

Hence:

39 players = 333.06 inches

1 players = x

Cross Multiply

39x = 1 × 333.06 inches

x = 333.06 inches/3

x = 8.54 inches

The amount of fabric was used on :

a) headband for each player = 15.88 inches of fabric

b) wristband for each player = 8.54 inches of fabric
