Answer:
Adult ticket is $6
Student ticket is $4, as you said.
Step-by-step explanation:
We'll call adult tickets x and student tix y.
14x + 11y = 128
14x + y = 88
First, solve the second equation for y in terms of x:
y = 88- 14x
Then substitute that for y into the first equation:
14x + 11(88-14x) = 128
14x + 968 - 154x = 128
-140x = -840
x = 6 The adult ticket is $6, like you said.
Now take that and solve for y:
y = 88 - 14(6)
y = 88 - 84
y = 4 The student ticket is $4, as you said.
Hope this helps. Feel free to ask questions so you can understand.

Answer:
<h2><u><em>
60° is your answer</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
180 - 70 = 110
110 = 12x + 2 + 15x
108 = 27x
108 : 27 = 4°
4 * 15 = 60° is your answer
check
15 * 4 + 12 * 4 + 2 + 70 = 180
60 + 48 + 72 = 180
the answer is good
