What is the solution to the rational equation x over 2x plus 1 minus 1 over 4 equals 2 over 2x plus 1
aalyn [17]
We want to solve
\frac{x}{2x+1} - \frac{1}{4} = \frac{2}{2x+1}

Subtract 2/(2x+1) from each side.
\frac{x}{2x+1} - \frac{2}{2x+1y} - \frac{1}{4} = 0

Add 1/4 to each side, and simplify the left side.
\frac{x-2}{2x+1} = \frac{1}{4}

Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1

Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2   or x = 4 1/2.

Answer:  x =  \frac{9}{2} \,\, or \,\, x = 4 \frac{1}{2}

Quick! Andrew has to play 15 games in a chess tournament. At some point during the tournament he has won half of the games he ha
nikklg [1K]

x - the number of the games he played

\dfrac{x}{2} - the number of the games he won

\dfrac{x}{3} - the number of the games he lost

x=\dfrac{x}{2}+\dfrac{x}{3}+2\Big|\cdot6\\6x=3x+2x+12\\x=12

15-12=3

<u>so, he has still 3 games to play</u>

Find the value of x. A. 53–√ in B. 241−−√ in C. 55–√ in D. 9
castortr0y [4]

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

{a}^{2}  =  {b}^{2}  +  {c}^{2}

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

{10}^{2}   =  {5}^{2}  +  {x}^{2}

{x}^{2}  =  {10}^{2}  -  {5}^{2}

{x}^{2}  = 100 - 25

{x}^{2}  = 75

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you
