System of equations:
w=(3/2)*h (1)
w*h=54 area (2)

w=54/h substitute into (1)
54/h=3h/2
3h²=54*2
h²= 36 (we take only positive solution)
h = √36=6
h=6 in.
w=(3/2)*h=(3/2)*6= 9
w=9 in.
correct answer is D

When Anna was born 16 years ago, her small town of Lewisville had a population of 15,000. The population has increased 11% each

Alex17521 [72]

15.000 ÷ 100

150 = 1%

1650 = 11%

1650 x 16 = 26.400

26.400 + 15.000 = 41.400

So 41.400 is the population number now.
