<span> <u>24 + 3x = 3x + 3(7 - 1)</u>
Eliminate the parentheses: 24 + 3x = 3x + 3(6)
24 + 3x = 3x + 18
Subtract 3x from each side: <em>24 = 18</em>
Look at that for a second. Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.
That's just another way to say: "The equation has NO solution."</span>
Answer is below.

<u><em>Step 1</em></u>
We'll to isolate the variable, but to do that, get rid of the coefficient that multiplies it.
To do that, divide both sides by 22.

<em><u>Step 2.</u></em>
Now we have divided both sides by 22, but we'll need to reduce the fraction
.
We can reduce the fraction by dividing the factors that are in the numerator and denominator.
That being said, 22 appears both in the numerator and denominator.

<u><em>Step 3</em></u>
Now, for
, we'll need to reduce it to the lowest terms. Like in the 2nd step, we'll divide factors that are in the numerator and denominator.
That being said, 2 appears both in the numerator and denominator.
Hence, M = 5/11
Answer:
D
Step-by-step explanation:
Call the first person A who can do the job in 5 hours.
Call the second person B who can do the job in 7 hours.
The formula for this problem is
Time = A*B/(A + B)
Time = 5*7 / (5 + 7)
Time = 35 / 12
Time = 2 hours and 11/12 of an hour.
The answer is D.
Answer:
B. -4
Step-by-step explanation:
The function only has one y-value: -4. That is the entirety of its range.
Answer:
B.) The initial cost is $12,950
Step-by-step explanation:
Given that:

is the function to represent the cost for a company for the production of a part for
number of days.
To find:
What does the value 12,950 represent in the above cost function.
Solution:
The given function contains two parts:
1. One part is multiple of
and
2. Second part is a constant.
Here,
is the number of days.
As
changes, the value also changes but the constant part remains the same.
Therefore, we can conclude that the initial cost for the company is $12,950.
The answer is:
B.) The initial cost is $12,950
