Senior tickets (x)
Child tickets (y)
First day: 3x + 5y = 70
second day: 12x + 12y = 216
Solve the system of equations (use elimination)
Multiply first equation by -4 -4(3x + 5y = 70), which makes it
-12x - 20y = -280
(+)12x + 12y = 216 add to second equation
-8y = -64
divide by -8. y = 8
Plugin the y value to either equation ( I will choose first equation)
3x + 5(8) =70
3x+ 40 = 70
3x = 30
x = 10
Senior tickets are $10, child tickets are $8
79 multiply .18 and you’ll get your answr
the answer of this question is postive
Answer:
61
Step-by-step explanation:
3x + 28
5x + 52
<u>+ 2x - 10 </u>
10x + 70 = 180º
x = 11
3(11) + 28 = 61º
