Answer:

simplifies to 6x+6=-10
x = -8/3 = -2 2/3

Step-by-step explanation:

3(4x+2)-6x=5x-5(2+x)

12x +6 -6x = 5x -10 -5x . . . . . eliminate parentheses using the distributive property

6x +6 = -10 . . . . . . . . . . . . . . . collect terms

x +1 = -10/6 . . . . . . . . . . . . . . . divide by 6

x = -1 - 5/3 . . . . . . . . . . . . . . . add -1

x = -8/3 . . . . . . . . . . . . . . . . . simplify

Bob and joe have a class together at Kensington college. They leave the class at the same time. Bob goes to the library at 4 mil

galben [10]

Solution

For this case we can create the following schema

We can use the definition of distance:

x= vt

We can find the relative velocity:

$V_{\text{rel}}=4-2=2\frac{mi}{hr}$

And the distance between both is required to be 2 mi so then we can find the time like this:

$t=\frac{x}{v_{\text{rel}}}=\frac{2mi}{\frac{2mi}{hr}}=1hr$

Then the answer is:

1 hr

The CFO of the company believes that an appropriate annual interest rate on this investment is 4%. What is the present value of

hodyreva [135]

Find attached the missing cash flow stream

Answer:

Present value = $1,685,334 (rounded to the nearest whole)

Explanation:

Since the cash flow stream is uneven, you must discount each stream individually and after you have discounted every stream you can add each preset value to find the net present value.

The formula for present value is:

$\text{Present Value} = \dfrac{\text{Future Value}}{(1+r)^n}\\\\\ Where:\\ \\ r = \text{Rate of return=interest rate}\\ \\ n = \text{Number of periods}$

1. Year 1:

Future value = $250,000
r = 4%
n = 1

$Present\text{ }value=\$250,000/(1+0.04)^1=\$240,384.62$

2. Year 2:

Future value = $20,000
r = 4%
n = 2

$Present\text{ }value=\$20,000/(1+0.04)^2=\$18,491.12$

3. Year 3:

Future value = $330,000
r = 4%
n = 3

$Present\text{ }value=\$330,000/(1+0.04)^3=\$293,368.80$

4. Year 4:

Future value = $450,000
r = 4%
n = 4

$Present\text{ }value=\$450,000/(1+0.04)^4=\$384,661.89$

5. Year 5:

Future value = $550,000
r = 4%
n = 5

$Present\text{ }value=\$550,000/(1+0.04)^5=\$452,059.91$

6. Year 6:

Future value = $375,000
r = 4%
n = 6

$Present\text{ }value=\$375,000/(1+0.04)^6=\$296,367.95$

Total present value = $240,384.62 + $18,491.12 + $293,368.80 + $384,661.89 + $452,059.91 + $296,367.95 + $ 296,367.95

Total present value = $1,685,334.29 = $ 1,685,334

Tony writes an equation to represent the distance he walks in meters, d, in relation to the number of minutes he walks, m. d = 1

liraira [26]

Tony : d = 108m.....so Tony walks 108 meters per minute

Mark :
(10,1100),(20,2200)
slope = (2200 - 1100) / (20 - 10) = 1100/10 = 110 meters per minute

So Tony's walk speed is 2 meters per minute slower then Tony's walk speed

The mean score of 8 players is 14.5. If the highest individual score is removed the mean of the score of the remaining 7 players

AfilCa [17]

Answer:

The highest score is 32.

Step-by-step explanation:

We are given the following in the question:

The mean score of 8 players is 14.5.

Let x denote the highest score.

If x is removed, the mean of the score of the remaining 7 players is 12.

Formula for mean:

$\bar{x} = \dfrac{\displaystyle\sum x_i}{n}$

Putting values, we get:

$14.5 = \dfrac{\displaystyle\sum x_i}{8}\\\\\Rightarrow \displaystyle\sum x_i = 116\\\\12 = \dfrac{\displaystyle\sum y_i}{7}\\\\\Rightarrow \displaystyle\sum y_i = 84\\\\\displaystyle\sum y_i = \displaystyle\sum x_i -x \\\\84 = 116 - x\\\Rightarrow x = 32$

Thus, the highest score is 32.
