Answer:
option a
Step-by-step explanation:
y^7/8 / y^1/4
First we will accommodate the fractions
1/4 = 2/8
y^7/8 / y^2/8
Then we will subtract the exponents of the powers since they have the same base and are dividing
7/8 - 2/8 = 5/8
y^5/8
Finally we pass the 8 as radical root
8√y^5

Answer:
The answer to your question is there were 88 children
Step-by-step explanation:
Data
Total number of people = 188
total cost = $5040
12 more adults than seniors
number of children = ?
adults = a
children = c
Process
1.- Write equations that help to solve this problem
a + c = 188 Equation l
a = c + 12 Equation ll
2.- Solve by substitution. Substitute equation equation ll in equation l
(c + 12) + c = 188
-Solve for c
c + 12 + c = 188
2c + 12 = 188
2c = 188 - 12
2c = 176
c = 176 / 2
c = 88
3.- Conclusion
There were 88 children
