1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20

Using scientific notation, it is found that the measure of one astronomical unit in kilometers is
A number in <em>scientific notation</em> is given by:
- In which
- To realize the conversion from decimal to scientific notation, b is the number of decimal places the comma moves, being positive if to the left, negative if to the right.
In this problem, 1 AU = 150,000,000 km.
- The comma has to move 8 places to the right, hence
Then, the measure is:

Answer:
Option B.
Step-by-step explanation:
we know that
The area of a circle is equal to
we have
substitute
Remember that
radians subtends the complete circle of area
so
by proportion
Find the area of the related sector for a central angle of radians
Let
x------> the area of the related sector
so ya I don't see it, it must be crazy
Slope: (y2-y1)/(x2-x1)
(11-5)/(-7+3) = 6/-4 = 3/-2
The slope is -3/2
