Answer:

x = -1

Step-by-step explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1

Total = 6,000.00 * 2.718281828^(.25)
Total = 6,000.00 * 1.2840254166

Ms. Rios wants to share $1 equally among 6 students. What fraction of a dollar will each student get?

Digiron [165]

Answer:

17 cents

Step-by-step explanation:

Firstly, as we know this is going to become a fraction, we can replace $1 with $1.00.
We are trying to divide $1.00 amongst 6 people. This is a division problem, and will look like 1.00 ÷ 6.
We get .166... which we can round to 17 cents, or .17.

If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
