Positive because a negative and a negative will always make a positive
Add 3 to both sides of the equation :<span>
</span> y = 3
Answer:
Y = 2/5z-6/5w
Step-by-step explanation:
6W + 5y = 2z
1. Subtract 6W from both sides
2. 5y = 2z-6W
3. Divide both sides by 5
4. y = 2/5z-6/5W
Answer:
5/9 of 90 = (5/9)(90) = 50
Step-by-step explanation:
Answer:
LHS of the given equation is:
sinθ+sin3θ+sin5θ+sin7θ=(sinθ+sin7θ)+(sin3θ+sin5θ)=2sin8θ2.cos6θ2+2sin8θ2.cos2θ2 [since sinC+sinD=2sinC+D2.cosC−D2=2sin4θ.cos3θ+2sin4θ.cosθ=2sin4θ.[cos3θ+cosθ] [since cosC+cosD=2cosC+D2.cosC−D2=2sin4θ.[2cos2θ.cosθ]=4cosθ.cos2θ.sin4θsinθ+sin3θ+sin5θ+sin7θ=(sinθ+sin7θ)+(sin3θ+sin5θ)=2sin8θ2.cos6θ2+2sin8θ2.cos2θ2 [since sinC+sinD=2sinC+D2.cosC-D2=2sin4θ.cos3θ+2sin4θ.cosθ=2sin4θ.[cos3θ+cosθ] [since cosC+cosD=2cosC+D2.cosC-D2=2sin4θ.[2cos2θ.cosθ]=4cosθ.cos2θ.sin4θ
