Answer:
20.
Step-by-step explanation:
We found the factors and prime factorization of 80 and 100. The biggest common factor number is the GCF number. So the greatest common factor 80 and 100 is 20
20
The factors of 80 are : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80
The factors of 100 are : 1, 2, 4, 5, 10, 20, 25, 50, 100
The common factors are : 1, 2, 4, 5, 10, 20
The greatest common factor is 20
The solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3
The compound inequality is given as:
6b < 36 or 2b + 12 > 6
Evaluate the like terms in the individual inequalities
6b < 36 or 2b > -6
Divide the individual inequalities by the coefficients of b
b < 6 or b > -3
Hence, the solution to the compound inequality given as 6b < 36 or 2b + 12 > 6 is b < 6 or b > -3

Solve with a system of equations
Let adult tickets be a and student tickets be s
1. 8a + 13s = 176
2. 4a + 4s = 68
3. s = 17 - a
Equation 2 is friendlier, so let's divide all the numbers by 4.
a + s = 17
Equation is s = 17 - a
Substitute s in equation 1
8a + 13(17-a) = 176
8a + 221 - 13a = 176
221 - 5a = 176
5a = 45
a = 9
The price of an adult ticket is 9 dollars
Hope this helps :)
