Answer:
9 is your answer for x.
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.
PEMDAS is the order of operations, & =
Parenthesis
Exponent (& Roots)
Multiplication
Division
Addition
Subtraction
First, subtract 13 & 8x from both sides:
2x (-8x) + 13 (-13) = 8x (-8x) - 41 (-13)
2x - 8x = -41 - 13
Simplify. Combine like terms:
-6x = -54
Isolate the variable, x. Divide -6 from both sides:
(-6x)/-6 = (-54)/-6
x = (-54)/(-6)
x = 9
x = 9 is your answer.

The operations referred to are likely
• raising to a <em>power</em> (the numerator of the exponent)
• taking a <em>root</em> (the denominator of the exponent)
• finding a <em>reciprocal</em> (because the exponent is negative)
They can be performed in any convenient order. It often works well to deal with small positive integers, so if one or more of these operations lets you proceed with a small positive integer for the remaining operations, that would be the one you'd perform first.

A computer performing operations with a negative rational exponent may do so using logarithms. That is, the log of the base will be multiplied by the exponent, then the antilog found. The exponent itself will likely be treated as a floating point number, unless coding specifically indicates otherwise.
<h2>Answer</h2>
Janice convert a mixed number to the wrong improper fraction
<h2>Explanation</h2>
To convert a mixed number to an improper fraction, we multiply the whole number by the denominator of the fraction and add the result to the numerator of the fraction; while keeping the denominator of the fraction as the denominator of the improper fraction.
Let's convert our mixed numbers to improper fractions:
To convert 
we multiply the whole number 10 by the denominator of the fraction 6, and then we add the result to the numerator 5:
Now let's convert 
:
Notice that Janice converted as 
, which is incorrect.
Since 
, we can conclude that Janice convert a mixed number to the wrong improper fraction.
