The <em>correct answer</em> is:
400,000.
Explanation:
The third digit in 399 is 9. To round to this place value, we inspect the digit behind it. If the digit is 5 or greater, we round up; if it is less than 5, we round down.
The digit behind 9 is 7. Since it is greater than 5, we round up. This would ordinarily put the number up 1; however, doing that makes the 9 a 10, which in turn makes the next number 10, and the next number 4. This gives us 400,000.
Answer:
<em><u>D</u></em><em><u>,</u></em><em><u> </u></em><em><u>122°F</u></em>

°F = 122
Answer:
x = 1/3
Step-by-step explanation:
Move all terms containing x to the left side of the equation.
8+6x=10
Move all terms not containing x to the right side of the equation
6x=2
Divide each term by 6 and simplify.
Exact Form:
x=1/3
Decimal Form:
x=0.3333333333
Hope this helps!
I came up with 7+5(x-1)
7 is a fixed one time cost.
5(x-1). x-1 because you have already charged $7 for the first hour.
Checking to make sure it is correct
so if a person stays 1 hour
7+5(1-1)
7+5(0) = 7
This answer makes sense because they get charged $7 the first hour
so say they stay 3 hours
7+5(3-1)
7+5(2) = 17
This answer makes sense because they get charges $7 for the first hour and $5 for the other 2. so 7+5+5=17.
we can see that the function works
