Formula for coordinates of midpoint,

x= (x1+x2)/2
y=(y1+y2)/2,

where (x1,y1), (x2,y2) coordinates of the end-points. 

-1=(x1-8)/2
-2=x1-8
x1=-2+8
x1=6

1=(y1+4)/2
2=y1+4
y1=2-4
y1= - 2

Question 8 of 10 (1 point)
LUCKY_DIMON [66]
3(n-8)=2n-2

3n-24=2n-2

Subtract 2n from both sides to get

n-24=-2

Adding 24 to both sides gives you

n=22. The number therefore is 22. Hope this helps!!!

I have 200 coins to put into 4 bags I put the coins into each bag so that each bag has 2 mote coins than the one before How many
Allushta [10]

First bag has 47 coins and second bag has 49 coins and third bag has 51 coins and fourth bag has 53 coins

<em><u>Solution:</u></em>

Given that,

Total number of coins = 200

Number of bags = 4

<em><u>I put the coins into each bag so that each bag has 2 more coins than the one before</u></em>

Therefore,

Each bag has 2 more coins than the one before. Based on this we can say,

Let "x" be the number of coins put in first bag

Then, x + 2 is the number of coins put in second bag

Then, x + 4 is the number of coins put in third bag

Then, x + 6 is the number of coins put in fourth bag

We know that,

Total number of coins = 200

x + x + 2 + x + 4 + x + 6 = 200\\\\4x + 12 = 200\\\\4x = 200-12\\\\4x = 188\\\\x = 47

Thus,

Coins put in first bag = x = 47

Coins put in second bag = x + 2 = 47 + 2 = 49

Coins put in third bag = x + 4 = 47 + 4 = 51

Coins put in fourth bag = x + 6 = 47 + 6 = 53

Thus number of coins in each bag are found
