Kaitlyn solved the equation for x using the following calculations. Negative 5.4 + x = 12.2. Minus 5.4. x = 6.8. What error, if any, did she make? She should have added 5.4 to each side. She should have added the inverse of 5.4 to each side. She made a computational error when she subtracted 5.4 from 12.2. She should have added 12.2 to each side.
Kaityn error is that (a) She should have added 5.4 to each side.
How to determine the error?The steps are given as:
-5.4 + x = 12.2
x = 6.8
The proper steps of the equation are:
-5.4 + x = 12.2
Add 5.4 to both sides
x = 17.6
Hence, Kaityn error is that (a) She should have added 5.4 to each side.

Kaitlyn solved the equation for x using the following calculations.
Her expression is,
-5.4 + x = 12.2
in her step, she subtracted -5.4 from both sides, this was her error because the correct step is to add 5.4 on both sides
And correct step will be,
x = 12.2 + 5.4
x = 17.6
Thus, She should have added 5.4 to each side. Option A is correct.

Find the original price given the total amount and tax or tip rate.
Total price: $307.32
Tax or tip rate: 20%
Enter the correct answer in the box.
Answer:$256.10
Step-by-step explanation:
x * 1.2= 307.32
X= 307.32/1.2
X= 256.1
The original price is $245.86.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Total price: n = $307.32
Tax or tip rate: 20%
Let m be the original price.
So,
Tax = Original Price x Tax %/100
Tax = 307.32 × 20/100
Tax = 307.32 x 0.2
Tax = $61.46
Original Price = Original Price - Tax
Original Price = 307.32 - 61.464
Original Price = $245.86
Therefore, $245.86 is the price.

Tell whether the statement is True or False.
316x - 2) - 7 = 18x - 13
Answer:
True.
Step-by-step explanation:
Multiply 3 by 6x-2 and you get (18x-6). Subtract 7 from -6 gives you 13, which equals 18x-13.
Answer:
True
Step-by-step explanation:
You want to get the x's by themselves, so first you have to use the distributive property.
3 x 6x = 18x
3 x 2 = 6
So now the equation should look like
18x - 6 - 7 = 18x - 13
So now you have to get the x's by itself by adding or subtracting like terms.
- 6 - 7 = -13
18x - (-13) = 18x - 13
+ (-13) + (-13)
-----------------------
18x = 18x
18/18 18/18
x = 1
Now plug the numbers in
3(6(1) - 2) - 7 = 18(1) - 13

A mouse traveled a total distance of StartFraction 3 Over 24 EndFraction of a mile in a maze over the past 3 hours. The mouse traveled the same distance each hour. To determine the distance that the mouse traveled each hour, Matt performed the calculations below.
StartFraction 3 Over 24 EndFraction divided by 3 = StartFraction 3 Over (24 divided by 3) EndFraction = StartFraction 3 Over 8 EndFraction
He concluded that the mouse traveled StartFraction 3 Over 8 EndFraction of a mile each hour. What is Matt’s error?
Answer:
Matt's error is that he just divided the denominator and not the numerator "
i got it right on edge
Step-by-step explanation:
Matt made the error as Matt should have divided the numerator but not the denominator of 3/24 by 3.
What is Fraction?The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.Given:
In 3 hours the mouse travelled = 3/24
So, Matt performed as 3/24 +3 = 3/ (24+3) = 3/8.
Now, Matt made the error.
Matt first have to divide the fraction 3/24 by 3 to get the distance covered in one hour.
Then, Matt should divide the Numerator not the denominator.
So, the distance traveled by mouse in one hour = 3/24 x 1/3 = 3/72 miles.

The lowest common multiple (LCM) of x and 120 is 360. Find the smallest possible value of x
Answer: The smallest possible value of x is 1
1 all the way to 360
120,240,360
As there is lowest common multiple of two digits is 360, in which one of the digits is 120 and other smallest possible value of x is 1.
What is the meaning of lowest common multiple?
The smallest positive integer that is divisible by both a and b is known as the least common multiple (lcm), lowest common multiple (lcm), or smallest common multiple (scm) of two numbers a and b in mathematics and number theory. Its standard abbreviation is lcm (a, b).
Integer division by zero is undefinable, hence this definition only applies if both a and b are not equal to zero. Since 0 is the only common multiple of a and 0, some writers define lcm (a,0) as 0 for all a, though.
Prior to performing any fractional operations like addition, subtraction, or comparison, the "lowest common denominator" (lcm) must be employed. x can have a value as low as 1, all the way up to 360.

[tex]\frac{InitialValue}{100} = \frac{x}{TaxPercentage}[/tex]
Substitute in our values, using No.1 as our example.
[tex]\frac{123.01}{100} = \frac{x}{7.5}[/tex]
Cross multiply
922.575 = x100
Solve for x by dividing by 100.
x = 9.22575
Now add x to the initial value.
9.22575 + 123.01 = 132.23575
