I am thinking of a number.

Hmmm......

Then, you must be thinking of 19.






Explanation:

Let you numher be x

now
according to question

multiply it by 8 and it becomes 8×x = 8x

Now add 22
so it becomes
8x + 22

now as told in the question take the same number again i.e x for one more time.

multiply it by 6
and you'll get 6x
and after adding 60 you'll get 6x + 60

Now again according to question
8x+ 22 and 6x+60 are same number therefore they must be equal,

8x+22 = 6x+60

Do a little azebra

8x -6x = 60 -22
2x = 38
x = 19.

and Tada, your number is here.

B is the midpoint of AC and E' is the midpoint of BD. If A(-9,-4), C(-1, 6), and E(-4,-3), find the coordinates of D.
Ipatiy [6.2K]
The coordinates for D are (-4, -7)

First we must locate point B as it is vital to finding the midpoint of BD. To do this, we take the average of the endpoints AC since B is its midpoint. 

x values = -9 + 1 = -8
Then divide by 2 for the average -8/2 = -4

y values = -4 + 6 = 2
Then divide by 2 for the average 2/2 = 1

Therefore B must be (-4, 1)

Now we know the values of E must be the average of B and D. So we can write equations for each coordinate since we know they are averages. 

x - values = (Bx + Dx)/2 = Ex
(-4 + Dx)/2 = -4 ---> multiply both sides by 2
-4 + Dx = -8 ---> add -4 to both sides
Dx = -4

y - values = (By + Dy)/2 = Ey
(1 + Dy)/2 = -3 ---> multiply both sides by 2
1 + Dy = -6 ---> subtract 1 from both side
Dy = -7

So the coordinates for D must be (-4, -7)

What is
ehidna [41]
To find slope subtract the two points in the coordinate (y). We have 8 and 4 so subtract those two. You get 8-4=4. Now start from the same coordinate expect this time subtract (x). Which is 9-3=6. You have 4/6 simplify and you get 2/3. Your slope is 2/3. Hope this helps
