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

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

60 + 3

63
