Answer:
n = -40/9
Step-by-step explanation:
Let n = the number
(1/2)n - 2/3 = (1/5)n - 2
Multiply both sides by 30, which will get rid of the fractions.
15n - 20 = 6n - 60
9n = -40
n= -40/9

Answer:
<h2>7. 62.8 sq.in.</h2><h2>8. 21.2 sq.in.</h2>
Step-by-step explanation:
The formula of an area of a triangle:
a, b - adjacent sides
θ - included angle
=============================================
7.
a = 9in, b = 14in, θ = 85°
sin85° ≈ 0.9962
Substitute:
8.
a = 12 in, b = 5 in, θ = 135°
sin135° = sin(180° - 45°) = sin45° ≈ 0.7071 <em>used sin(180° - x) = sin(x)</em>
Substitute:
