Answer:
x ≥ 8
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define inequality</u>
-36x - 24 ≤ -6(5x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -6: -36x - 24 ≤ -30x - 72
- Add 36 on both sides: -24 ≤ 6x - 72
- Add 72 on both sides: 48 ≤ 6x
- Divide both sides by 6: 8 ≤ x
- Rewrite: x ≥ 8
Here we see that any number <em>x</em> greater than or equal to 8 would work as a solution.
Volume of cylinder:
Formula: pi * r^2 * h
r = 2, h = 20
pi * 2^2 * 20
pi * 4 * 20 = 20pi
Solution: A
Answer:
Step-by-step explanation:
<u><em>Add 3 to both sides of the equation:</em></u>
<u><em>Solve the square root:</em></u>
<em> {add 1 to both sides}</em>
<u><em>hope this helps.......</em></u>
Answer:
