X= number of adult tickets
y=number of child tickets.
we can suggest this system of equations:
x+y=118 ⇒x=118-y
7.5x+3y=696
we can solve this system of equations by substitution method:
7.5(118-y)+3y=696
885-7.5y+3y=696
-4.5y=-189
y=-189/-4.5
y=42
x=118-y
x=118-42
x=76
Answer: the number of adult tickets sold was 76.

12 and 13 are consecutive numbers
12+13=25
hence, 12 and 13 are your answers
Answer:
C. cot theta
Step-by-step explanation:
(csc theta -cot theta )/(sec theta -1)
csc = 1/ sin
cot = cos / sin
sec = 1 / cos
Let x = theta
(1/ sin x -cos x / sin x )/(1/ cos x -1)
Getting a common denominator in the denominator and combining terms
(1- cos x)/ sinx / ( 1 - cos x) / cos x
(1- cosx) (1- cosx)
----------- ÷ ------------
sinx cos x
Copy dot flip
(1- cosx) cosx
----------- * ------------
sinx 1 -cos x
Cancel like terms
cos x / sin x
cos / sin = cot
cot x
cot theta

Step-by-step explanation:
Answer:
Sin A: 35/37
Cos C: 35/37
Step-by-step explanation:
Sin A: 35/37
Cos C: 35/37
Using acronym SohCahToa we know
Sin is Opposite/Hypotenuse
Cos is Adjacent/Hypotenuse
With each problem we mark by the letter given to create adjacent side.
I hope this helps!
