A company loses $5,400 as the result of a manufacturing defect. Each of the 8 owners have agreed to contribute an equal amount, x, to help pay for the losses.Part A
Which expression shows the total loss after the owners contribute some money?
–5400 + 8x
5400 – 8x
–5400 ÷ 8x
–5400 × 8x
Part B
How much did each owner contribute if the total loss is $600 after their contributions?
$480
$675
$600
$500

Answers

The amount the company loses is expressed as a negative number to

indicate the direction of the cash flow.

Correct responses:

  • Part A: -5,400 + 8·x
  • Part B: $600

Methods used for arriving at the above responses

The amount the company loses = $5,400

Number of owners = 8

Amount each owner agree to contribute to pay for the losses = x

Part A

The loss of the company = $5,400

The amount lost can be expressed as -5,400

The amount by which the loss is reduced after all contributions = 8·x

The expression that shows the total loss after the owners contribute some money is therefore;

  • -5,400 + 8·x

Part B

The total loss after all contributions = $600

Therefore;

-600 = -5,400 + 8·x

8·x = 5,400 - 600

x = (5,400 - 600)/(8) = \mathbf{600}

  • The amount each owner contributed, x = $600

What is 24x^2y^6-16x^6y^2+4xy^2 divided by 4xy^2?

Answers

24x^2y^6-16x^6y^2 = 8y^4x^4 +4xy^2

8y^4x^4 +4xy^2 = 12y^6x^5 / 4xy^2

12y^6x^5 / 4xy^2 = 3y^4x^4  ... I think that is the answer! :)
