Answer:
(a) Step 2. 9x -12 = 13 +2x
Step-by-step explanation:
The distributive property says a factor outside parentheses multiplies each term inside parentheses. It is an error to do addition of the factor, or to miss multiplying a term.
In Step 2 of this "solution", the factor of 3 is erroneously <em>added</em> to each coefficent inside parentheses. It should be <em>multiplied</em>.
Correct Step 2: 9x -12 = 13 +2x
__
The rest of the solution should be ...
Step 3: 9x -2x = 13 +12
Step 4: 7x = 25
Step 5: x = 25/7
___
<em>Check</em>
3(3(25/7) -4) = 8 + 2(25/7) +5
3((75 -28)/7) = 13 +50/7
141/7 = 141/7 . . . . . answer checks OK
Answer:
$52.5
Step-by-step explanation:
Whenever there is a sales tax of a certain percentage, you need to first convert that percentage to decimal. 5%=0.05, and multiplying this by the overall price gives 0.05*50=$2.5. Adding this to the initial price of $50, you get 50+2.5=$52.5. Hope this helps!

Answer:
There are 47.12 liters in 12.4 gallons of gasoline.
Option C is correct option.
Step-by-step explanation:
Total Gasoline bought = 12.4 gallons
We are given:
1 gallons = 3.8 liters
So.=, we need to find how many liters in 12.4 gallons of gasoline
1 gallon = 3.8 liters
12.4 gallon = 3.8*12.4
= 47.12 liters
So, there are 47.12 liters in 12.4 gallons of gasoline.
Option C is correct option.
The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.
<h3>What is an absolute function?</h3>
The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x |
If the value inside the mode operator is greater than zero, then simply the mode operator is eliminated.
The notation of the absolute function is given below.
|x - y| If x>y
Then the absolute function is given as,
|x - y| = x - y
The absolute expression |x - y| is rewritten in the form of without using absolute value notation will be x - y.
