What was the error in this equation?

Mathematics
1 answer:
PtichkaEL [24]3 years ago
3 0

Answer:

The error is the solution.

The solution is all real numbers, or infinite amount of solutions.

Step-by-step explanation:

Step 1: Write equation

-4(2n - 3) = 12 - 8n

Step 2: Solve for <em>n</em>

  1. <u>Distribute -4:</u> -8n + 12 = 12 - 8n
  2. <u>Subtract 12 on both sides:</u> -8n = -8n
  3. <u>Add 8n to both sides:</u> 0 = 0

Here we see that <em>n</em> can equal any number. If you plug in any number <em>n</em>, it will render the equation true. Therefore, our solution is n = infinite amount of solutions.

n = 0 is only slightly correct. 0 does work as the solution, but there are solutions as well.

GarryVolchara [31]

The cost of next model car is $ 33136.

Step-by-step explanation:

Given,

The cost of current model car is $38000

The next model car is 12.8% less than the current model.

To find the cost of next model

Formula

If the price of object is $x and it decreases r% for next year, the value o the object for next year is = $ x×(100-r)%

So,

The cost of next model = $ 38000×(100-12.8)%

= $ 38000×87.2%

= $ 33136

seraphim [82]

It will take Mallory 40 minutes to get to the airport by train.

Step-by-step explanation:

Given,

Time taken by car = 120 minutes

Time taken by train = t

According to given statement;

Time taken by car = 3 times time taken by train

120=3t

Dividing both sides by 3

\frac{120}{3}=\frac{3t}{3}\\40=t\\t=40

It will take Mallory 40 minutes to get to the airport by train.
