63/240 seats or 21/80
The greatest common denominator is 3, so you would divide both by 3.

(2x+1)/2=(x+2)/5<br><br>if possible can you show me step by step how to get the answer <br>

katrin2010 [14]

Answer:

$\boxed{\bold{Decimal \ Form: \ x \ = \ -0.125}}$

$\boxed{\bold{Fraction \ Form:x=-\frac{1}{8}}}$

Step By Step Explanation:

Apply Fraction Cross Multiply: If $\bold{\frac{a}{b}=\frac{c}{d}:then\ a\cdot \:d=b\cdot \:c}$

$\bold{\left(2x+1\right)\cdot \:5=2\left(x+2\right)}$

$\bold{\left(2x+1\right)\cdot \:5: \ 10x+5}$

$\bold{2\left(x+2\right): \ 2x+4}$

$\bold{10x+5=2x+4}$

Subtract 4 From Both Sides

$\bold{10x+5-5=2x+4-5}$

Simplify

$\bold{10x=2x-1}$

Subtract 2x From Both Sides

$\bold{10x-2x=2x-1-2x}$

Simplify

$\bold{8x=-1}$

Divide Both Sides By 8

$\bold{\frac{8x}{8}=\frac{-1}{8}}$

Simplify

$\bold{x=-\frac{1}{8}}$

Turn Fraction Into Decimal

$\bold{-1 \ \div \ 8 \ = \ -0.125}$

$\bold{-0.125}$

Cot? 2x + cos2x + sin’ 2x = csc? 2x<br> Need help with 40

kkurt [141]

Answer:

$\rule{100mm}{0.1mm}$

$\cot^2(2x)+\cos^2(2x)+\sin^2(2x)=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +[(\cos^2(2x)+\sin^2(2x)]=\csc^2(2x)$

$\dfrac{\cos^2(2x)}{\sin^2(2x)} +1=\csc^2(2x)$

$\dfrac{\cos^2(2x)+\sin^2(2x)}{\sin^2(2x)}=\csc^2(2x)$

$\dfrac{1}{sin^2(2x)} =\csc^2(2x)$

$\boxed{\csc^2(2x)=\csc^2(2x)}$ ✔

$\rule{100mm}{0.1mm}$
