Let x = Class A
Let y = Class B
Let z = Class C
Equations from problem:
x - 160 = y
2/3x = z
y + 92 = z
Solving through substitution:
2/3x = y + 92
2/3x = (x - 160) + 92
2/3x = x - 68
-1/3x = -68
3(-1/3x) = 3(-68)
-x = -204
x = 204
Now substitute x in the first equation to get y:
204 - 160 = y
44 = y
44 = Class B
There are 44  folded paper cranes in Class B.

Lostsunrise [7]

Given:

The number of total students = 200

The number of students like cooking = 61

The number of students who like reading = 32

The number of students who like both cooking and reading= 19

The number of students who like video games = 73

The number of students who like cooking and video games= 23

The number of students who like reading and video games = 92

The number of students who like all 3 hobbies = 6

NO ONE EVER HELPS ME , PLEASE HELP ME I NEED HELP!
Makovka662 [10]

Answer:

A is the answer  

12 in

first substitute the variables

then 78=1/2h(5 + 8)

this makes it an equation

add similar terms which equals to

78=1/2xhx13

then divide both sides by 13

6=1/2xh

lastly divide both sides by 1/2

12=h

Step-by-step explanation:

proof

A=1/2x12(5 + 8) then

A=1/2x12x13  then

   A=6x13  then

       A= 78in^2

Answer:

x=7

Step-by-step explanation:

first, add 12 to both sides so it would look like: 6x-12+12=30+12

so, ya get 6x=42

then you divide 6 from both sides, and that is: 6x/6=42/6

so x=7

Graph the image of the given triangle under a dilation with a scale factor of 1/3 and center of dilation (0, 0) .
Vinil7 [7]

We are given : A scale factor of 1/3 and center of dilation (0, 0).

For the given image, the coordinates of the vertices of the triangle are

(0,9), (0,0) and (-6,0).

We can apply formula for finding new coordinates:

Scale factor * [Vertex coordinates of the given image - Coordinate of Center of dilation] +Coordinate of Center of dilation.

Applying same formula to each coordinates we are given.

(0,9) --> 1/3 [ (0,9) - (0,0) ] + (0,0) ]  = 1/3 [ (0,9)] +(0,0) = (0,3).

(0,0) --> 1/3 [ (0,0) - (0,0) ] + (0,0) ]  = 1/3 [ (0,0] +(0,0) = (0,0).

(0,9) --> 1/3 [ (-6,0) - (0,0) ] + (0,0) ]  = 1/3 [ (-6,0)] +(0,0) = (-2,0).

Now, we can plot those resulting coordinates on the graph and form a triangle.
