5xy-10x

5x are both common, so take that as a factor:

5x(y-2)

And so

5xy-10x = 5x(y-2)

Answer:

Step-by-step explanation:

the mean is adding up all the numbers, then dividing by the amount of the numbers.

add up all the numbers:

13 + 13 + 14 + 18 + 22 = 80

the mean is 23.

so you need to back track:

23 * 6 = 138

138 - 80 = 58

The Red Line in the figure is an altitude of triangle hjl. Using right angle trig and properties of equality, y sin L = x = z si

aivan3 [116]

Answer:

$\Large \boxed{\mathrm{\bold{C}}}$

Step-by-step explanation:

$\sf \displaystyle sin(\theta) =\frac{opposite}{hypotenuse }$

$\sf \displaystyle sin(L) =\frac{x}{y}$

$\sf \displaystyle sin(H) =\frac{x}{z}$

$\displaystyle \sf \frac{sinL}{z} =\frac{sinH }{y}$

$\displaystyle \sf \frac{\frac{x}{y} }{z} =\frac{\frac{x}{z} }{y}$

Simplifying the expression.

$\sf \displaystyle \frac{x}{yz } = \frac{x}{yz} \ (true)$

$\displaystyle \sf \frac{z}{sinL} =\frac{y}{sinH}$

$\displaystyle \sf \frac{z}{\frac{x}{y}} =\frac{y}{\frac{x}{z}}$

Multiplying both sides by x.

$\sf yz=yz \ (true)$

The area of a circle is 254.34. Find the radius

Evgesh-ka [11]

Answer:

Step-by-step explanation:

area of a circle = pi times radius^2

254.34= 3.14 X r^2 get rid of 3.14 by dividing both sides by 3.14

254.34/3.14= r^2

81= r^2

find the square root of 81=9

Find the sum of the measures of the intereor angles of each convex polygon.

serious [3.7K]

Step-by-step explanation:

To find the sum of the measures of the intereor angles of each convex polygon

we using formula

$(x - 2)180°$

we can put the value of x is 54

then,

$\longrightarrow \: (54 - 2) \times 180°$

$\longrightarrow \: 52 \times 180°$
$\longrightarrow \: 9360°$

we can put the value of x is 19

then,

$\longrightarrow \: (19 - 2) \times 180°$
$\longrightarrow \: 17 \times 180°$
$\longrightarrow \: 3060°$

we can put the value of x is 292

then,

$\longrightarrow \: (292 - 2) \times 180°$
$\longrightarrow \: 290 \times 180°$
=》 52200°

we can put the value of x is 5

then ,

$\longrightarrow \: (5 - 2) \times 180°$
$\longrightarrow \: 3 \times 180°$
=》 540°
