The correct answer will be: $31 = $4a + $3s (y = mx + b) meaning if Mr. Steele buys 4 adults tickets then he also bought 5 student tickets. $31 = 4(4) + 3(5) -- 31 = 16 + 15 -- 31 = 31
To solve 1/3 -1/6, you need to make the fractions have the same common denominator. So since the denominator 3 needs to become 6, multiply 1/3 by 2 and you get 2/6.
So 2/6 -1/6 = 1/6
The correct answer is A.

The area of the triangle = 1/2 * base * altitude = 1.2 * 20 * a = 10a
Work out the altitude (a):-
the altitude forms a right angled triangle with vertex angle = 1/2*108 = 54
so tan 54 = 10 / a
a = 10 / tan 54 = 7.265
area of the triangle = 10 * 7.265 = 72.65 cm^2
