Step Number 1. Subtract 5 from the whole equation.

Step Number 2. Simplify

Step Number 3. Divide the whole equation by -2

Step Number 4. Simplify

Done! :)
-5n - 8(1+7n) = -8
-5n - 8 - 56n = -8
-61n = 0
n = 0
First you have to find common denominators for all the Fractions. (witch should be 24 for the denominators) Then add 6 21/24 + 1 12/24 = 8 9/24, Then take 8 9/24 - 3 4/24 and you should get the answer 5 5/24

Answer:
35.6 yd²
Step-by-step explanation:
Area of ∆UVW can be solved if we know the lengths of 2 sides and their included angle.
We are Given just 1 side, UV (w). Use the law of sines to find UW (v).
Thus:

W = 137°
w = 19 yd
V = 180 - (137 + 22) = 21° => sum of triangle
v = ??
Plug in the values and solve for v

Multiply both sides by sin(21)


(approximated)
Find area of ∆UVW:
Area = ½*UV*UW*sin(U)
Area = ½*v*w*sin(U)
= ½*10*19*sin(22)
Area = 35.6 yd² (to nearest tenth)
