x = 6

given

\frac{x+2}{x-2} = \frac{4}{8}

cross- multiply to obtain

8(x + 2) = 4(x - 2) ( distribute parenthesis on both sides )

8x + 16 = 4x - 8 ( subtract 4x from both sides )

4x + 16 = - 8 ( subtract 16 from both sides )

4x = - 24 ( divide both sides by 4 )

x = \frac{-24}{4} = - 6

Hello there!

<u><em>Answer: ⇒ x=-6</em></u>

_________________________________________________________

Step-by-step explanation:

Apply fraction cross multiply.

(x+2)*8=(x-2)*4

Expand.

8x+16=4x-8

Subtract by 16 from both sides of equation.

8x+16-16=4x-8-16

Simplify.

8x=4x-24

Subtract by 4x from both sides of equation.

8x-4x=4x-24-4x

Simplify.

4x=-24

Divide by 4 from both sides of equation.

\frac{4x}{4}=\frac{-24}{4}

Simplify it should be correct answer.

x=-6

Ryder Industries is considering a project that will produce cash inflows of $92,000 a year for five years. What is the internal
RSB [31]

Answer:

20.02%

Step-by-step explanation:

Formula : NVP = 0 =-P_0 + \frac{P_1}{(1+IRR)} + \frac{P_2}{(1+IRR)^2} + . . . +\frac{P_n}{(1+IRR)^n}

P_0 = 275000

n = 1,2,3,4,5

Substitute the values in the formula :

0 =-275000 + \frac{92000}{(1+IRR)} + \frac{92000}{(1+IRR)^2} + \frac{92000}{(1+IRR)^3}+\frac{92000}{(1+IRR)^4}+\frac{92000}{(1+IRR)^5}

275000 = \frac{92000}{(1+IRR)} + \frac{92000}{(1+IRR)^2} + \frac{92000}{(1+IRR)^3}+\frac{92000}{(1+IRR)^4}+\frac{92000}{(1+IRR)^5}

Solving for IRR using calculator

IRR = 20.02

Hence the internal rate of return if the initial cost of the project is $275,000 is 20.02%

CAN SOMEONE JUST PLEASE ANSWER THIS ASAP FOR BRAINLIEST!!!
Rom4ik [11]
A=lw
42xy^3=(14xy)l
isolate l
divide both sides by 14xy to isolate l
(42xy^3)/ (14xy)=14xy / 14xy *l
the 14xy in the right cancel out
now you have:
42xy^3/14xy=l
42/14= 3, now just do division of powers for xy
x-x =0x, y^3-y= y^2
therefore the answer is 3y^2
