132 = 1/2x + 2(x - 9)
132 = 1/2x + 2x - 18
132+ 18 = 2.5x
150 = 2.5x
150/2.5 = 60......price of adult ticket
a childs ticket is 9 less then adults......so 60 - 9 = 51 <== childs ticket

Step-by-step explanation:

(
x

)
From here we can just FOIL; first, outer, inner, last. Multiply the first term in the first bracket (x), by the FIRST term in the second bracket (x), giving us
x
2
. Then, we multiply the outermost term on the left side by the OUTERmost on the right side, giving us
−
3
⋅
x
, equal to
−
3
x
. We then multiply the INNERmost terms together, which are again -3 and
x
, giving us
−
3
x
again. Finally we multiply the LAST term in the first bracket by the last term of the second, giving us
−
3
⋅
−
3
, or 9. Then, we simply write these out, in order:
x
2
−

Collect like terms:

x
+
9
And you're done!
Answer: x=-4
Step-by-step explanation:
Since the lines are parallel they have the same angle so you can set them equal to each other.
x+54=50
x=50-54
x=-4
