Answer:

The reasonable first step would be to distribute.

Step-by-step explanation:

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

4x+3x+6=10x-15

7x+6=10x-15(subtract 7x from left side, to the right side, add 15 to the left side)

21=3x (Divide both sides by 3)

7=x

What would the answer be for this equation 7x/20 - 5x/12

hodyreva [135]

Answer:

$\frac{1}{15} x$

Step-by-step explanation:

$\frac{7x}{20} - \frac{5x}{12}$

$\frac{3 \times 7x}{3 \times 20} - \frac{5 \times 5x}{5 \times 12}$

$\frac{21x}{60} - \frac{25x}{60}$

$\frac{21x - 25x}{60} = (21 - 25)x = - 4x$

$\frac{ - 4x}{60} = - \frac{ x}{15}$

$\boxed{\green{= \frac{1}{15} x}}$

Linkin Corporation is considering purchasing a new delivery truck. The truck has many advantages over the company’s current truc

Romashka [77]

Answer:

Payback is 7.3 years

NPV $3,099

Step-by-step explanation:

The formula for payback period period=initial investment/annual cost savings

The initial investment is the amount of cash outflow that would be required to purchase the new delivery truck,which is $54,750,while on the other hand the annual cost savings is $7,500

cash payback period=$54,750/$7,500=7.3 years

Ordinarily,the expected payback is 1/2 of 8 years=4 years.

The net present is the present worth of the future cost savings as well as the scrap value of the truck in year 8,calculated by multiplying the cash flows with the discounted factors for relevant years as below:

Years cash flow DCF at 8% Present values

0 -$54,750 1 -$54,750

1-7 years $7500 5.2064 $39,048

8 $34,800 0.54027 $18,801

NPV $3,099

Note that the $34,800 =$7500+$27300

The year 1-7 factor is annuity factor for 8% 7 years
