Answer:
First number: 71/7
Second number: 135/7
Third number: 270/7
Step-by-step explanation:
First number = x
Second number= 2x-1
Third number= 2(2x-1)
x+(2x-1)+2(2x-1)= 68
3x-1+4x-2=68
7x-3=68
7x=71
x=71/7
You can check by plugging in the x into the equation.

Answer
0.75 or 3/4 is the answer (degree)
I just solved for the angles and use a graphing calculator to find the din and cosine values and multiply them
the answer is 762 adults and 694 students.
762 x 5.00 = 3810
694 x 2.50 = 1735
now add 3810 + 1735 = 5545
