D. Multiply the top equation by 2

That way, 3y(2) - 6y = 6y - 6y = 0

hope this helps

8x + 3y = 2....multiply by 2
4x - 6y = -7
--------------
16x + 6y = 4 (result of multiplying by 2)
4x - 6y = -7
----------------add
20x = - 3.......and u can see, the y's have been eliminated
x = -3/20

so ur answer is : multiply top equation by 2 <=

Answer:

the cash flow from operation is $267,397

Step-by-step explanation:

Given that

Revenues be $876,223

General and admin expense $352,479

Depreciation expense $131,455

Leasing expense $108,195

Interest expense $78,122

Tax rate is 34%

We need to find out the cash flow from operation

As we know that

Cash flow from operation = (Revenue - general & admin expense - depreciation - leasing - interest) × (1 - tax rate) + depreciation

= ($876,223 - $352,479 - $131,455 - $108,195 - $78,122) × (1 - 0.34) + $131,455

= $205,972 × (1 - 0.34) + $131,455

= $267,397

Hence, the cash flow from operation is $267,397

Select the correct answer. Which expression represents the series ? 1+5+25+125+625? creating and solving formulas for geometric
Art [367]

Answer:

The given series can be written as

4

∑  (5)^i

i = 0

We know that the series  is

1+5+25+125+625

This is equal to

(5)^0 + (5)^1 + (5)^2 + (5)^3 + (5)^4

Thus,

For i from 0 to 4,

We get the general representation.

PLZ ANSWER URGENT<br> A).1+ 4x+2/2x=5x<br> b).2x-2+3x/4=2x
Elena L [17]

A.

Divide the numbers

1 + 4x 2/2 • x =5x

1 + 4x + 1x =5x

Multiply by 1

1 + 4x + 1x=5x

Combine like terms

1 + 4x + x =5x

1 + 5x =5x

Subtract 1 from both sides of the equation

5x + 1 = 5x

5x + 1 - 1 =5x -1

Simplify

Subtract the numbers

5x = 5x -1

Subtract 5x from both sides of the equation

5x = 5x -1

5x - 5x = 5x -1 -5x

Simplify

0= -1

Result

0= -1
