The price of one share of Acme Company declined $3.50 per day for 4 days in a row. What is the overall change in price of one share?

Answers

Answer:

The overall change in price of one share is: -$14.00

Step-by-step explanation:

The Acme Company share has declined its price in a rate of $3.50 per day

Therefore the change rate is: - (\mathdollar 3.50)/(day)

In order to find the overall change in prince in 4 days in a row, we must have to multiply the change rate by 4 days

( - (\mathdollar 3.50)/(day))(4 \ days)= - \mathdollar 14.00

Therefore, the overall change in price is: -$14.00

Since it's a decline, the amount will be negative.
3.5 per day for 4 days so multiply 3.5 by 4, which equals: $14
so the overall change is -$14.00

12-x=15
What does x equal?

Answers

12-x=15 \n \n -x = 15 - 12 \n \n -x = 3 \n \n x = -3 \n \n

The final result is: x = -3.

Ok. First you isolate the variable. So Ill take 12 which is posotive, and subtract 12 from the 15 and the 12. Now all were left with is -x=3. We multiply each side by -1 to give us x=-3. Hope this helps!

Multiply (2.4 ⋅ 1014) ⋅ (4 ⋅ 107). Express the answer in scientific notation

Answers

You multiply 2.4 with 4 to get 9.6. Then 10^14 times 10^7 and you should get 10^21. Since the number 9.6 is between 1 and 10, you don't do anything with the exponent. So the scientific notation would be 9.6 x 10^21. :)

9.6*10^21 is your answer
