Answer:

Step-by-step explanation:

4) 35x + 28y =7*5*x + 7*4*y = 7(5x + 4y)

5) Cost of top = $9

Cost of 3 top = 9*3 = $27

Cost of skirt = $x

Cost of 3 skirt = 3x

Cost of 3 skirt and 3 top = 3x + 27

Cost of 2 skirt = 2x (as she bought 5 skirts)

Cost of her purchase = Cost of 3skirt &3 top and 2skirt

= (3x + 27) + 2x

= 5x +27

6) Cost of 5 nail polish bottle = 5p

Cost of two lip gloss tube = 2g

Cost of one gift bag = 5p + 2g

Cost of 8 gift bag = 8* ( 5p + 2g)

=8*5p + 8*2g

= 40p + 16g

AB and CD intersect at point E if measure angle AED equals 6x-24 and measure angle CEB equals 4y+32 find the values of x and y s

Zolol [24]

The values of x and y such that AB is perpendicular to CD will be 19 and 14.5.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

AB and CD intersect at point E.

If measure angle AED equals 6x – 24 and measure angle CEB equals 4y + 32.

Then the values of x and y such that AB is perpendicular to CD will be

6x – 24 = 90

6x = 114

x = 19

Then we have

4y + 32 = 90

4y = 58

y = 14.5

Sin^2(x/2)=sin^2x <br> Find the value of x

Veronika [31]

$\sin^2\dfrac x2=\sin^2x$
$\dfrac{1-\cos x}2=1-\cos^2x$
$1-\cos x=2-2\cos^2x$
$2\cos^2x-\cos x-1=0$
$(2\cos x+1)(\cos x-1)=0$
$\implies\begin{cases}2\cos x+1=0\\\cos x-1=0\end{cases}$ $\implies\begin{cases}\cos x=-\frac12\\\cos x=1\end{cases}$

The first case occurs in $0\le x$ for $x=\dfrac{2\pi}3$ and $x=\dfrac{4\pi}3$ . Extending the domain to account for all real $x$ , we have this happening for $x=\dfrac{2\pi}3+2n\pi$ and $\dfrac{4\pi}3+2n\pi$ , where $n\in\mathbb Z$ .

The second case occurs in $0\le x$ when $x=0$ , and extending to all reals we have $x=2n\pi$ for $n\in\mathbb Z$ , i.e. any even multiple of $\pi$ .
