Answer:
∠ CBD = 63°
Step-by-step explanation:
∠ ABC + ∠ CBD = ∠ ABD, substitute values
7x - 9 + 6x + 27 = 96, that is
13x + 18 = 96 ( subtract 18 from both sides )
13x = 78 ( divide both sides by 13 )
x = 6
Thus
∠ CBD = 6x + 27 = 6(6) + 27 = 36 + 27 = 63°
48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
54: 1, 2, 3, 6, 9, 18, 27, 54

Y = a(1 - r)^t
Y = 8,000(1 - 0.06)^t
You can see a = 8,000
As the fish population starts at 8,000
The expression is 9*
+2+
.
9*
+2+
---> First square
by squaring the top and bottom number.
=9*
+2+
---> Multiply 9 and
=1+2+
---> Add
=3
---> Optional: turn into improper fraction
