Answer:

\boxed{ \bold{  \huge \boxed{ \sf{x = 18.5}}}}

Step-by-step explanation:

\sf{3(22 + 2) = 18 + 4(x - 5)}

Add the numbers : 22 and 2

⇒\sf{3 \times 24 = 18 + 4(x - 5)}

Multiply the numbers : 3 and 24

⇒\sf{72 = 18  + 4(x - 5) }

Distribute 4 through the parentheses

⇒\sf{72 = 18 + 4x - 20}

Calculate the difference

⇒\sf{72 =  - 2 + 4x}

Swap the sides of the equation

⇒\sf{ - 2 + 4x = 72}

Move 2 to right hand side and change it's sign

⇒\sf{4x = 72 + 2}

Add the numbers : 72 and 2

⇒\sf{4x = 74}

Divide both sides of the equation by 4

⇒\sf{ \frac{4x}{4}  =  \frac{74}{4} }

Calculate

⇒\sf{x = 18.5}

Hope I helped!

Best regards!!

Answer:

x=18.5

Step-by-step explanation:

3(22+2) =18 + 4(x-5)

3(24) = 18 + 4(x-5)

72=18+4(x-5)

4(x-5)+18=72

4x-20+18=72

4x= 72-18+20

4x=72+2

4x=74

x=74/4

x=18.5

Calculate had a net income of 5 million dollars in 2010, while a small competing company, Computate, had a
Julli [10]

9514 1404 393

Answer:

  a) see the attached spreadsheet (table)

  b) Calculate, for a 10-year horizon; Computate for a longer horizon.

  c) Year 13; no

Step-by-step explanation:

a) The attached table shows net income projections for the two companies. Calculate's increases by 0.5 million each year; Computate's increases by 15% each year. The result is rounded to the nearest dollar.

__

b) After year 4, Computate's net income is increasing by more than 0.5 million per year, so its growth is faster and getting faster yet. However, in the first 10 years, Calculate's net income remains higher than that of Computate. If we presume that some percentage of net income is returned to investors, then Calculate may provide a better return on investment.

The scenario given here is only interested in the first 10 years. However, beyond that time frame (see part C), we find that Computate's income growth far exceeds that of Calculate.

__

c) Extending the table through year 13, we see that Computate's net income exceeds Calculate's in that year. It continues to remain higher as long as the model remains valid.

SVEN [57.7K]

Answer:

<em>A) Be sure the task is understood. </em>

Step-by-step explanation:

The principle "Make sure the mission is understood, performed, and achieved."

<em>Another way we talk about this principle in the Navy is through the idea of "intrusive leadership." In some respects both "micromanagement" and "intrusive leadership" sound terrible. </em>

Think about certain great managers and leaders you have had in your career yet again. Probability are they will be the ones who asked you those difficult questions, too.

They moved everyone to new technical levels, and eye for detail. When you said you knew what you were doing or when you announced the progress of a project, they didn't necessarily take it to face value.
