A new car worth $28,000 is depreciating in value by $4,000 per year. After how many years will the car's value be
$12,000?

After .. (4 years, which is the answer) the cars value will be at 12,000. i got it correct

Answers

It will be after 4 years

After 4 years the value or the cost of car will be $12,000.

Depreciation refers to the decrease in the value of an asset over time due to various factors such as wear and tear, obsolescence, or changes in market conditions.

It is a common concept used in accounting and finance to allocate the cost of tangible assets (such as buildings, machinery, vehicles, etc.) over their estimated useful lives.

Given:

Car cost = $28,000

Depreciation per year  = $4,000

Since the car's value is depreciating by $4,000 per year,

Subtract $4,000 from the initial value of $28,000 each year.

= $28,000 - $4,000 - $4,000 - $4,000 - $4,000

= $12,000

Therefore, after 4 years the car is $12,000.

3x-6 = (4x-8)/2/3. 4x:2/3 = 12/2 =6x -8:2/3 = - 24/2= - 12

Refer to the graphic novel frame below. Seth traveled 1 miles in 57.1 secs. About how fast does Seth travel miles per hour?

Answers

In order to find miles per hour we must first change the time given to us (57.1 seconds) into hours. We will do this by first changing the seconds to minutes:

57.1 seconds / 60 = .952 minutes

Now we can change our minutes to hours:

.952 minutes / 60= .016 hours

Now to find miles per hour we divide the miles by our time:

1 mile / .016 hours = 63.04 mph

What's the difference between like and unlike algebraic expressions

Answers

Answer:

In algebra,

• Like terms are terms having the same literal (variable) with same exponents.

Example: 5y + 8y are like terms because they are both "y".

• Unlike terms are terms having the same variable with different exponents or different variable with same exponents.

Example: 4x + 19y are unlike terms because x and y are two different variables with different coefficients.

Answer:

- The equation that represent the cost C of renting a car and driving x miles is C = $39.11 + $0.50x

- $130 can travel 181.32 miles

Step-by-step explanation:

From the question, a rental company rents a luxury car at a daily rate of 39.34 ​$ plus​ $.50 per mile, that is

$0.50 is added to the initial $39.34 for every mile.

The equation that represent the cost C of renting a car and driving x miles is

C = $39.34 + $0.50x

Now, to determine how many miles 130$ can travel,

we will put C = $100, and determine x in the above equation

$130 = $39.34 + $0.50x

$130 - $39.34 = $0.50x

$90.66 = $0.50x

x = $90.66/$0.50

x = 181.32

Hence, $130 can travel 181.32 miles
