12/15
Divide 12 by 15 and then you should get 0.8
0.8 is obviously equal to 8/10ths or 80%
Hope this helps :)
Answer:
sin(4π/21)
Step-by-step explanation:
Step 1: Rearrange expression
sin(π/3)cos(π/7) - cos(π/3)sin(π/7)
Step 2: Use sin(A ± B)
sin(π/3 - π/7)
Step 3: Evaluate
sin(4π/21)
And we have our answer!
Answer:
c) 6× (9+8) = (6 × 9) + (6× 8)
Step-by-step explanation:
<u><em>Distributive property of multiplication</em></u>
The distributive property of multiplication
a(b+c) = a b + a c
(a+b)c = ac + bc
6× (9+8) = (6× 9) + (6×8)
2x - 3y = 9
- 3y = -2x + 9
y = (-2x + 9)/-3
slope = -2
Since the slope is negative the line passes through quadrants 2 and 4
Therefore the answer is b.
