Answer:
solution is b= -7.3
Step-by-step explanation:
-5.4b = -5.9b - 3.65
-5.4b + 5.9b = - 3.65
0.5b = - 3.65
b = - 3.65÷ 0.5
b = - 7.3
So you have 5 sides you can add 2/5+2/5+2/5+2/5+2/5 = 10/5 = 2 miles around the park. Or you can multiply 5 sides (pentagon) times each side of 2/5 mile thus..... 5*2/5 = 10/5 = 2 so this is also 2 miles around the perimeter.
B. 30
$39(4) + $34.30 = $1200
$156 + 34.30 = $190.30
$1200 - $190.30 = $1009.70
$1009.70 / $34.30 = 29.437
