Circumference = pi * diameter
Diameter = 15
Assume pi = 3.14
15 * 3.14 = 47.1 in.
The answer is A
⁹P₃=9×8×7=504; ¹⁰C₄=10×9×8×7÷(4×3×2×1)=210.
Answer:
There is no solution.
Rewrite -2x + y = -6 so it starts with y =...
y = 2x - 6
Substitute that in 2/3x - 1/3y = -2 gives:
2/3x - 1/3*(2x -6) = -2
2/3x - 2/3x + 2 = -2
0 + 2 = -2
This statement is not true, and that means there is no solution.
It would be B because eaxh section either repeats itself or is close to repeating its previous part
