<h3>Answer</h3>
1/81(C)
<h3>Step-by-step solution</h3>
(3)^4=81
if 3^-1=1/3
so, 3^-4=1/81(C)
Okay so you must do the (18-7) first so with that you will get
8*[5+11]/11
next you do the parenthesis yet again so [5+11]=16
8*16/7
and then you simplify
I got : 18.28.
Answer:
12 fish
Step-by-step explanation:
You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.
= x
= x
12 = x
