Answer: a = 15
Step-by-step explanation:
6a + 10 = 3a + 55
Subtract 10 from both sides
6a = 3a + 45
Subtract 3a from both sides
3a = 45
Divide each side by 3
a = 15
I think you meant to write
(2 × 10⁶) × 0.00009
First, convert 0.00009 to scientific notation:
0.00009 = 9 × 10 ⁻⁵
Then
(2 × 10⁶) × 0.00009 = (2 × 10⁶) × (9 × 10 ⁻⁵)
… = (2 × 9) × (10⁶ × 10 ⁻⁵)
… = 18 × 10¹
… = 1.8 × 10²
