Answer:

b=-17

Step-by-step explanation:

1) add common terms aka 5 and 12, which is 17

b+17=0

2) move seventeen to the other side by doing the opposite opperation of addition which is subtraction

b=-17

Answer:

Sum: 17 + 11 = 28

Difference: 17 - 11 = 6

Step-by-step explanation:

The sum of x and y is 28. In other words, x plus y equals 28 and can be written as equation A:

x + y = 28

The difference between x and y is 6. In other words, x minus y equals 6 and can be written as equation B:

x - y = 6

Now solve equation B for x to get the revised equation B:

x - y = 6

x = 6 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 28

6 + y + y = 28

6 + 2y = 28

2y = 22

y = 11

Now we know y is 11. Which means that we can substitute y for 11 in equation A and solve for x:

x + y = 28

x + 11 = 28

X = 17

Summary: The sum of two numbers is 28 and their difference is 6. What are the two numbers? Answer: 17 and 11 as proven here:

Sum: 17 + 11 = 28

Difference: 17 - 11 = 6

Answer:

17 +11 = 28

Step-by-step explanation:

Answer: 4.3 × 10^6 meters, and 4.3 × 10^9 millimeters.

Explanation: In order to find the scientific notation of a large number, you want to move the decimal point to the left until you only have one digit to the left of the number, then you can count the spaces you have moved, and this will make the power of 10 that you'll add to the end. This seems a little confusing, but let's look at it through the example.

Step 1) Move the decimal point to the left until there's only one digit to the left of the decimal:

4,300,000 turns into 4.300000

Step 2) Count the number of digits you've moved.

Above, we moved 6 spaces to the left.

Step 3) Add the decimal to the front, and then 10^the number of spaces you moved

4.3 (from step one) × 10^6 (from step two)

= 4.3 × 10^6

It works the same way for the millimeter question, just convert meters into millimeters before you start the problem, and then solve it using the steps above! I hope this helped you :)

The scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

It is a way of writing very large or very small numbers where a number between 1 and 10 is multiplied by a power of 10.

Example:

310,000,000 can be written in scientific notation as 3.1 ✕ 10^8.

We have,

Distance = 4,300,000 meters

1 meter = 1000 millimeters

So,

4,300,000 meters = 4,300,000,000 millimeters

We can write 4,300,000 in scientific notation as:

= 4.3 x [tex]10^{6}[/tex] meters

We can write 4,300,000,000 millimeters in scientific notation as:

= 4.3 x [tex]10^{9}[/tex] millimeters

Thus the scientific notation in meters and millimeters are

- 4.3 x [tex]10^{6}[/tex] meters

- 4.3 x [tex]10^{9}[/tex] millimeters

Step-by-step explanation:

Answer:AB = 5/2 and CD = 2/-5, perpendicperpendicular

Step-by-step explanation:

0+5 = 5

2+2=4

8-5=3

Answer: 41

Step-by-step explanation:

The horizontal line beneath the angle created is always 180 degrees. Because you are given two equations for each angle created, simply write: 180= (3x-3) +(x+19). This gives you 4x+16=180, of which you subtract 16 to 180 which gives you 164. Finally, divide both sides by 4: 4x/4=164/4 and you will get 41. Hopefully I was of aid to you.

Answer:

Example 1 is 25%

Example 2 is 3.5%

Example 3 could be $10,464.41  See attached.

Step-by-step explanation:

Example 1

An increase of sales to $9,500 is an increase of:

Sales increase = ($9,500 - 7,600) / $7,600

Sales increase = .25, or 25%

Assuming costs and assets increase proportionally, the pro forma financial statements will look like this:

Pro forma income statement Pro forma balance sheet

Sales $ 9,500.00 Assets $ 23,875.00 Debt $ 7,000.00

Example 2.

Return on equity (ROE) is a measure of financial performance calculated by dividing net income by shareholders' equity. Because shareholders' equity is equal to a company’s assets minus its debt, ROE is considered the return on net assets. ROE is considered a gauge of a corporation's profitability and how efficient it is in generating profits.

Example below given on 2nd example is 60% payout ratio type question with constant debt equity ratio.

Return on equity 34008 / 90400 = 0.37619469

A / S = $ 34,008 / $ 90,400 = 37.6%

L / S = $ 9,040 / $ 90,400 = 10%

Change in Sales or ΔSales = $ a - $ 90.400 = $ b

EFN = (.376 x $ b) - (.10 x $ b ) - ((profit margin x $ a) x (1 - .dividend payout ratio))

Formula EFn = 0 = full subtraction of EFN

Example 3 - Calculation of the EFN:

Total Assets last year = $ 6.5 Million

Total Sales last year = $ 21.0 Million

Total Current Liabilities last year = $ 2.1 Million

Profit Margin = 4% of sales

Forecasted Sales = $ 24.5 Million

Dividend Payout Ratio or d = 60%

A / S = $ 6.5 / $ 21.0 = 31%

L / S = $ 2.1 / $ 21.0 = 10%

Change in Sales or ΔSales = $ 24.5 - $ 21.0 = $ 3.5

EFN = (.31 x $ 3.5) - (.10 x $ 3.5) - ((.04 x $ 24.5) x (1 - .60))

EFN = $ 1.085 - $ .35 - ($ .98 x .40)

EFN = $ .735 - $ .392

EFN = $ .343

Answer:

  k = 2

Step-by-step explanation:

The slope formula gives the slope between two points:

  m = (y2 -y1)/(x2 -x1)

  -2 = (-2 -0)/(3 -k)

Multiplying by (3 -k) gives ...

  -2(3 -k) = -2

  3 -k = 1

  k = 3 -1 = 2

The value of k is 2.

Answer:

Therefore, the values of "x" and "y" are -1000/312 and -115/39 respectively.

Step-by-step explanation:

[tex] \sf \leadsto 8x - 7y = -5 - - - (i)[/tex]

[tex] \sf \leadsto -x + 4y = -15 - - - (ii)[/tex]

By first equation,

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x = -5 + 7y[/tex]

[tex] \sf \leadsto x = \dfrac{-5 + 7y}{8} [/tex]

Now, we can find the original value of y.

[tex] \sf \leadsto -x + 4y = -15[/tex]

[tex] \sf \leadsto \bigg( \dfrac{-5 + 7y}{8} \bigg) + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y}{8} + 4y = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 7y + 32y}{8} = -15[/tex]

[tex] \sf \leadsto \dfrac{-5 + 39y}{8} = -15[/tex]

[tex] \sf \leadsto -5 + 39y = -15(8)[/tex]

[tex] \sf \leadsto -5 + 39y = -120[/tex]

[tex] \sf \leadsto 39y = -120 + 5[/tex]

[tex] \sf \leadsto 39y = - 115[/tex]

[tex] \sf \leadsto y = \dfrac{ - 115}{39} [/tex]

Now, we can find the original value of x.

[tex] \sf \leadsto 8x - 7y = -5[/tex]

[tex] \sf \leadsto 8x -7 \bigg( \dfrac{ - 115}{39} \bigg) = -5[/tex]

[tex] \sf \leadsto 8x + \dfrac{805}{39} = -5[/tex]

[tex] \sf \leadsto \dfrac{312x + 805}{39} = -5[/tex]

[tex] \sf \leadsto 312x + 805 = -5(39)[/tex]

[tex] \sf \leadsto 312x + 805 = -195[/tex]

[tex] \sf \leadsto 312x = -195 - 805[/tex]

[tex] \sf \leadsto 312x = -1000[/tex]

[tex] \sf \leadsto x = \dfrac{-1000}{312} [/tex]
