Answer:
12
Step-by-step explanation:
This can be solved by working backwards.
7 is one more than half the number of invitations.
Subtract 1. 6 is half the number of invitations.
Double.
12 is the full number of invitations.
Algebra (if you must!):
x = number of invitations
x/2 + 1 = 7
Subtract 1.
x/2 = 6
Multiply by 2.
x = 12
This is for 2.X=22 so the total angle is 90° and you take away 68° and that leaves you with 22°
Ooo I don’t speak that language
7.
15/2= 7.5
you cant get 7 and a half action figures so round down to 7
