Answer:

My answer is 8.428571429 ~ 8.43.

Step-by-step explanation:

First you can find log 5 which is 0.698970004 ~0.7. then you can use it to multiply the numbers in the bracket which will be 0.7x(x-7)=1...which will be 0.7x-4.9=1...then you will collect like terms which will be 0.7x=1+4.9 then it will be 5.9÷0.7 which will be equal to my answer above..Thank you for the question

Round 10.95 to the nearest tenth
Serhud [2]

Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.

The answer is 11.0 or just 11.

<em>Ed: Explanation below.</em>

<em />

11.00

10.99

10.98

10.97

10.96

10.95 Look at the 9. Then look to the right. Do I round up or down?

10.94

10.93

10.92

10.91

10.90

If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.

Therefore, the answer is 11.

Why might working with n a commission basis make dealing with finances more difficult?
Lady_Fox [76]

Answer: The commission is paid according to sales amounts that are likely to vary from month to month.

Step-by-step explanation: Instead of a salary that is paid in the same amount on a schedule, the commission may be very large one month and very small or zero at other times.

Financial planning usually includes monthly payments that and predictable expenses for food, transportation, utilities, etc. The person who earns a commission must remember to set aside some of the "extra" to cover these expenses. And be prepared to work more or harder at some times to make sales when they don't come easily.
