1. −12=n3−6 What is n?

2. n+6−4=10

3. n−2−3=−6

Step-by-step explanation:

1.  -12=-6

    =6-12

    =-6

    n=

    n=-1.82

2. n+6-4=10

   n=10+4-6

   n=8

3. n-2-3=-6

   n=2+3-6

   n=-1

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.
