Step-by-step explanation:
Since y varies directly with x,
y = kx, where k is a real constant.
When x = 4, y = 32.
=> (32) = (4)k, k = 8.
Therefore when x = -2,
y = kx = (8)(-2) = -16.
Answer: 9.2•10^7 kilometers
Step-by-step explanation:
5.8•10^7=58,000,000
1.5•10^8=150,000,000
150,000,000-58,000,000=92,000,000
92,000,000=9.2•10^7
