Step-by-step explanation:
0.00067=67X10^5 so
67X10^5-2.3X10^5
64.7X10^5 which can be expressed as:
6.47X10^6
(not sure if it matters to you or not, but technically we only had two significant figures so it should be rounded to 6.5X10^6)
Answer:
k < 3/7
Step-by-step explanation:
Step 1:Sinplify both sides of the inequality
10k <-4k+6
Step 2: Add 4k to both sides
10k + 4k < -4k + 6 + 4k
14k < 6
Step 3:Divide both sides by 14
14k/14 < 6/14
k <3/7
