Morgan Bowie is trying to determine the amount to set aside so that he will have enough money on hand in 3 years to overhaul the

Nostrana [21]

Answer:

$468.09

Step-by-step explanation:

first we must calculate the expected future value of the engine overhaul:

($390 x 10%) + ($570 x 30%) + ($750 x 50%) + ($790 x 10%) = $39 + $171 + $375 + $79 = $664

now we must determine the present value of $664 using a 6% interest rate:

PV = FV / (1 + r)⁶ = $664 / 1.06⁶ = $468.09

How do we solve this? (No need to find x)

Genrish500 [490]

Answer:

Hi,

Step-by-step explanation:

We can't solve that but reduce it to the same denominator.

$\dfrac{x+5}{x}+\dfrac{x+8}{x-1}\\\\=\dfrac{(x+5)(x-1)+x(x+8)}{x(x-1)}\\\\=\dfrac{x^2+5x-x-5+x^2+8x}{x(x-1)}\\\\=\dfrac{2x^2+12x-5}{x(x-1)}\\$

Solve the inequality x + 2 1/2 > -1/2. Graph the solution set on a number line.show your work.

antiseptic1488 [7]

Answer:

x > - 3

Step-by-step explanation:

x + 2 $\frac{1}{2}$ > - $\frac{1}{2}$ First turn 2 $\frac{1}{2}$ into an fraction since its easier. So it becomes $\frac{5}{2}$

x + $\frac{5}{2}$ > - $\frac{1}{2}$

- $\frac{5}{2}$ - $\frac{5}{2}$ Do inverse operations, so subtract $\frac{5}{2}$ from both sides.

x > - $\frac{6}{2}$ Combine - $\frac{5}{2}$ with - $\frac{1}{2}$ , which gives us - $\frac{6}{2}$

x > - 3 Since we know that 6 divided by 2 is 3.

This would not allow me to attach an image so I am going to type a visual representation f what the graph would look like below)

<-------------O--------------------------------------------------->

-5 -4 -3 -2 -1 0 1 2 3 4 5

So, the number line would be a solid line rather than dashed (but I was not able to attach an image so I kind of had to improvise). When using ≥ ≤ sings the circle of the point is closed. When using < and > signs, the circle of the point is open. Thus, in this scenario since he sign is >, then the circle of the point is open. The direction of the arrow and ray for this equality is going to the right because the answer is that x is greater than - 3, Therefore any values greater than - 3 are a possibility which is why the arrow goes on indefinitely.

Evaluate. 10⋅[(6+4)÷2

ipn [44]

You have to pay close attention to the Order of Operations.

10(6+4)/2. Grouping symbols first.
6+4=10.
10(10)/2
10*10=100.
100/2.
50 is your answer.
