ST = 52

SW = 54

WV = 54

Step-by-step explanation:

Because TW is a median line, that means that SW and WV are the same length. So, SW = WV or:

2x + 30 = 5x -6

We can then rearrange to have all the x's on one side like so:

2x - 2x + 30 = 5x -2x -6

30 = 3x -6

30 + 6 = 3x -6 +6

36 = 3x

Then, we divide both sides by 3 to find x by itself:

12 = x

To finish, replace x with 12 in each equation:

ST = 12 + 40

ST = 52

SW = 2(12) + 30

SW = 24 + 30

SW = 54

WV = 5(12) -6

WV = 60 -6

WV = 54

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies

i have not got your picture clearly so see it once again
