What was the error in this equation?
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 n
Distribute -4: -8n + 12 = 12 - 8nSubtract 12 on both sides: -8n = -8nAdd 8n to both sides: 0 = 0Here we see that n can equal any number. If you plug in any number n, 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.

An art gallery owner purchases art at flea markets and sells the art for a 14% profit in the gallery. If the owner purchases a piece of art for $885 at a flea market, what will be its selling price in the gallery?
Answer:
$1008.9
Step-by-step explanation:
Given
Cost of piece of art = $885
Percent profit made = 14%
Profit amount = 14% of $885
Profit amount = 14/100×885
Profit amount = 12390/100
Profit amounts to $123.90
Selling price = cost price + profit amount
Selling price = $885+$123.90
Selling price = $1008.9
Hence the selling price for the art at the gallery is $1008.9
Answer:
$1008.9

Answer:
57°
Step-by-step explanation:
A triangle's angles should all add up to 180°
So you have to add up the other two given angles, so in this case it is 60° + 63°, which equals 123°. Then you subtract 123 ° from 180°, giving you the answer of 57°.
Answer:
it's 57
Step-by-step explanation:
the 3 angles add up to 180 so add the 2 angles together to get 123 and then subtract that from 180

-(x-7) + (5/3) = 2(x+9) wht does x equal
Answer:
-28/3=x
Step-by-step explanation:
-(x-7) + (5/3) = 2(x+9)
-x+7+5/3=2x+18
7+5/3=2x+18-x
7+5/3=x+18
5/3=x+18-7

What is mathematical equation?
Equation is defined as the state of being equal and is often shown as a math expression with equal values on either side, or refers to a problem where many things need to be taken into account. An example of an equation is 2+2 = 3+1.
In the given equation,
2m = −6n −5
Divide by 2 on both sides, we get
2m/2 = −6n/2 −5/2
m = -3n - 5/2
Therefore, our value of m is in terms of n, which is -3n - 5/2

You deposit $900 in a savings account that earns a simple interest rate of 4.5% per year. You calculate you will earn $1215 in interest over 3 years. Is your answer reasonable?
A. Yes; the interest will be much less than the total in the account
B. No; the interest will be much less than the total in the account.
C. No; the interest will be more than the total in the account.
D. Yes; the interest will be more than the total in the account.
Answer:
a..
Step-by-step explanation:
yes the interest will be much less than total than the account
The answer is not reasonable because the interest will be much less than the total in the account.
In order to determine if the answer is reasonable, we have to determine the simple interest that would be earned and the total amount in the account.
Simple interest = amount deposited x time x interest rate
$900 x 0.045 x 3 = $121.50
The total amount in the account in three years = amount deposited + interest earned
$900 + $121.50 = $1021.50.
