A b^3
B is x^2
I think unless you need to keep it in the fraction so x^6/x^3
1. thousands place value 3000
2. 3 hundred thousand value 300,000
The problem can be modeled like this:
x - 6 + 7 = 65
x + 1 = 65
x = 64
The number is 64. Since -6 + 7 = 1, you could have also simplified the question to, "A number is 65 when you add 1. What is the number?"
The net would look like a square surrounded with four triangles, one on each side.
I think the question for this problem is to formulate an equation that could describe the behavior of the trend. To do this, let's see the trend first. In the first hour, the number of transactions is 10. In the 2nd hour, the transactions is 2(10) = 20. In the third hour, the transactions is 20(2) = 40. So, we can see that the trend is 10, 20, 40, 80, ....and so on. You notice that this is a geometric progression, where r=2. Thus, the equation for this will be:
Number of transactions = 10(r)ⁿ⁻¹ = <em>10(2ⁿ⁻¹), where n is the number of hours</em>
