Answer:
5 • 10^6
Step-by-step explanation:
When we talk about approximations, it is important to know that their purpose is not to find the correct value, only close enough that will do the job. We use them when we want to write something in a shortened way, to save time or when it's impossible to find precise value. Of course, our approximation won't be 100% precise, but it will be acceptable.
So, in this case, we are dealing with a population that is just above five million.
Milion (1 000 000) is a seven-digit number written with six zeros, so its power of ten will be 10^6 (ten to the power of six).
Since the population is around five million, we will approximate it to
5 • 10^6 (five times ten to the power of six)

Answer:
Choice 3: David's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings.
Step-by-step explanation:
In the question, $12,350 is given as the initial value and '240x' is the monthly spending in terms of x.. When writing the equation, we must subtract 240x because the money is being spent.
The correct equation for this situation would be:
y = 12,350 - (240x).
Thus, David's Equation is correct.
Answer:
d
Step-by-step explanation:
3/7x+5=8
subtract 5 from both sides
3/7x=3
multiple 7/3 from both sides to cancel out 3/7 and get x alone
x= 7
