Step-by-step explanation:
Total portions are
5+4+3
12
One portion,
4860 / 12
405
So
5 : 4 : 3
5*405 : 4*405 : 3:405
2025 : 1620 : 1215
= 3x(x^2-9)
= 3x(x+3)(x-3)
answer is B. second choice
Answer:
z ≥ 2
Step-by-step explanation:
Step 1: Write inequality
-7z - (-5z - 4) ≤ -3z - 2 + 4z
Step 2: Solve for <em>z</em>
- Distribute negative: -7z + 5z + 4 ≤ -3z - 2 + 4z
- Combine like terms: -2z + 4 ≤ z - 2
- Add 2z to both sides: 4 ≤ 3z - 2
- Add 2 to both sides: 6 ≤ 3z
- Divide both sides by 3: 2 ≤ z
- Rewrite: z ≥ 2
