Answer:
Third one
Step-by-step explanation:
30x would be 30 times the amount of fish (x)
+ 80y would be 80 times the amount of octopus captured (y)
- 15z would be subtracting 15 times the amount of crabs she captures
3.2-3x+7
6-3x+7
-7 -7
-1= -3x divide both sides by -3
x=0.3
Well since area is length time width
and we alreadt have the width and the area
all we have to do is divide 3392 by 32
so lets do the math:)
3392 ÷ 32 = 106
so the length is 106!
hope this helps:)
