N is between A and X. AN = 2x + 1, NX = 3x, and AX = 21. what is AN?

Answer:

128.6

Step-by-step explanation:

I just did the math

HERE I TOOK PICTURES

i only understand number 11

Step-by-step explanation:

Let the number of psychology books be 'x'.

and that of sociology books be 'y'.

x + y = 317 (given)

Number of sociology books sold was 89 less than that of psychology books.

y = x - 89

Which means,

x + x - 89 = 317

2x = 317 + 89

2x = 406

x = 406/2 = 203

y = 203 - 89 = 114

Hence, 203 psychology books and 114 sociology books were sold.

Answer:

5 is the median

Step-by-step explanation:

By crossing out the points on each side one by one, you could find that 5 is the median.

Answer:

#12.) 3m+2=17

3(5)+2=17

5*3=15

15+2=17

Step-by-step explanation:

Answer:

3 x 2 + 5 - 4 = 7 if its not 7 then try 15 most likely 7

m = 5 its already given on the top or its 17

7 x 5 - 2 > 12, m = 5 or the answer is 33 for the left side

for this you need to draw an empty circle on two and make the line bold starting from 2 to the 10.

Explanation:

If y varies inversely as x, the two variables can be represented in an equation in the form

y

=

k

x

where

k

is some constant.

We are given that

y

=

5

when

x

=

6

. We can plug this into the above equation to find what

k

is:

5

=

k

6

=

k

Based on this we can create our equation:

y

=

x

And then find

x

when

y

=

P.PENEEEEEEEE,TE GUSTAA∞[tex]\pi \sqrt{x} x^{2} \neq \alpha \sqrt[n]{x} \sqrt[n]{x}[/tex]

Answer:

A 2.2

Step-by-step explanation:

So the perimeter is 10.5 and one side is 1.7 and the others are the same.

The Equation for the perimeter of a pentagon is P = side + side + side + side + side.

Fill it out for the sides.

10.5 = 1.7 + 4h

8.8 = 4h

h = 2.2

Answer:

henry gets 231

Step-by-step explanation:

my head

Answer:

231

Step-by-step explanation:

Let's consider that Gavin got X pounds.

Then Henry gets 3 times as much as Gavin => 3X

And Mark gets twice as much as Henry => 2 * 3X

Together they get 770, so:

X + 3X + 2*3X = 770

10X = 770  =>  X = 77

As we mentioned, Henry gets 3X, so

3X = 3 * 77 = 231

Answer:

60%

Step-by-step explanation:

8-5=3

3/5=0.6 and 0.6 = 60%

so 3 is 60% or 5

so 5+3 is a 60% increase

Answer:

r/6 +2 = X

Step-by-step explanation:

We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)

r + 2 +4 = 3x

r + 6 = 3x

To find the X, we get rid of the 3, so divide both sides by 3

r/3 + 6/3 = x

r/3 + 2 = x

OR

(r+6)/3 = x

Both works : )

Answer:

Step-by-step explanation:

We want to solve r + 2 = 3x – 4 for x.

This means isolating x on one side.  To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:

r + 6 = 3x

Finally, divide both sides by 3:

        r + 6

x = -------------

Answer:

363.1

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

The Area of sector is π cm². so option D is correct.

The sector of a circle is like a slice of a circular pizza.

[tex]A = \dfrac{x \times \pi r^2}{360} \: \rm unit^2 area[/tex]

Mathematically π  radians = 180 degrees

thus, π /6 radians =  180/6 = 30 degrees

The formula for the length of an arc is;

Ф/360 x 2πr

where Ф, is 30 degrees

And the arc length is pi

so we have

30/360 x 2πr = π

30/360 x 2r = 1

60r = 360

r = 360/60

r = 6 cm

Now the area of a sector is;

Ф/360 x πr^2

30/360 x π36

= π cm^2
