1 3/5 goes between 1 and 2
Answer:
Corp A. 320,000
Corp B. 40,000
Corp C. 430,000
Corp C owns the most land, Corp A owns 8 times more land.
Explanation:
3.2.• 10^5 = 3.2 • 100,000 = 320,000
4 • 10^4 = 4 • 10,000 = 40,000
4.3 • 10^5 = 4.3 • 100,000 = 430,000
40,000 < 320,000 < 430,000
320,000 ÷ 40,000 = 8
The steps involving properties of equality are shown in painful detail.
For Step 4, you add 7 to both sides of the equation (with the goal of cancelling the -7 on the left). So you have
6x -7 +7 = 12 +7 . . . . . . . showing 7 added to both sides
In the next step, this is simplified to the way you might have written it to start with:
6x = 19
There should be no confusion in any of this. All solutions of all equations make use of the properties of equality like this. Addition is used to cancel subtraction, division is used to cancel multiplication. (Root-taking cancels powers, and vice-versa; inverse trig functions cancel trig functions; and so on.)
Answer:
a trend line can be used to make predictions in real-world situations (the third option)
Explanation:
the first & second options are wrong because it is not a requirement for a trend line to pass through any given data point.
the fourth option is wrong because a trend line shows the general upward/downward trend of the data, and may not necessarily touch all of the data points.
the third option is correct because a trend line helps to roughly estimate the trend (hence the name) of the graph, which allows us to make predictions in real-world situations.
i hope this helps! :D
