2x + 5 > 9 and 5x ≤ 30
- 5 - 5 5 5
2x > 4 x ≤ 9
2 2
x > 2
Solution Set: {2 < x ≤ 9}, (2, 9]
Answer:
Answer:
1). Option (A)
2). Option (A)
Step-by-step explanation:
1). A worker bee has the mass = 0.00011 kg
In scientific notation we can convert the mass of bee as,

Option (A) is the answer.
2). An African elephant has a mass = 8139 kg
In scientific notation,
8139 = 8.139 × 10³

Therefore, 8139 kg = 8.139 × 10³ kg
Option (A) is the answer.
