Solving Rational equations. LCD method. Show work. Image attached.

Dmitry [639]

Answer:

$b=1$

Step-by-step explanation:

The given rational equation is

$\frac{2b-5}{b-2} -2=\frac{3}{b+2}$

The Least Common Denominator is $(b+2)(b-2)$ .

Multiply each term in the equation by the LCD.

$(b+2)(b-2)\times \frac{2b-5}{b-2} -(b+2)(b-2)\times2=(b+2)(b-2)\times\frac{3}{b+2}$

Simplify;

$(b+2)\times \frac{2b-5}{1} -2(b+2)(b-2)=(b-2)\times\frac{3}{1}$

$(b+2)(2b-5) -2(b+2)(b-2)=3(b-2)$

Expand and group similar terms

$2b^2-5b+4b-10 -2(b^2-4)=3b-6$

$2b^2-5b+4b-10 -2b^2+8=3b-6$

$-b-2=3b-6$

$3b+b=-2+6$

$4b=4$

$b=1$

Translate the algebraic expression shown below into a verbal expression. Fraction with variable x in numerator and 6 in the deno

Sveta_85 [38]

Fraction with variable x in numerator and 6 in the denominator can written in the algebraic expression as $\frac{x}{6}$

Let's assume some number is n.

So, the sum of six and some number can be written as 6+n.

The product of six and some number can be written as 6*n.

The quotient of some number and six will be n/6.

The difference of six and some number will be 6-n.

ankoles [38]

Answer:

0.17155425219941%

Step-by-step explanation:

100%/x%=682/1.17

(100/x)*x=(682/1.17)*x - we multiply both sides of the equation by x

100=582.90598290598*x - we divide both sides of the equation by (582.90598290598) to get x

100/582.90598290598=x

0.17155425219941=x

x=0.17155425219941
