Answer:
The expression equivalent to -3( m + 5) is
c) - 3m - 15
Step-by-step explanation:
Answer: After washing 20 cars together, each team will have raised the same amount in total.
Step-by-step explanation:
Let x represent the number of cars that each each teams will wash for them to raise the same amount in total.
The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. This means that the total amount raised by the volleyball team after washing x cars would be
4x + 24
The wrestling team has raised $84 in the past, and they are making $1 per car today. This means that the total amount raised by the wrestling team after washing x cars would be
x + 84
For both amounts to be equal, the number of cars would be
4x + 24 = x + 84
4x - x = 84 - 24
3x = 60
x = 60/3
x = 20
Slope is undefined as the answer is 6/0
We can check the equation is an extraneous solution or not by finding the solution and plugging it in the equation, to verify it.
<h3>What is the extraneous solution?</h3>
In mathematics, an extraneous solution is a solution that comes from the process of solving the problem but is not a genuine solution to the problem, such as the answer to an equation.
As we know from the definition the extraneous solution is a solution that comes from the process of solving the problem but is not a genuine solution to the problem.
Let's suppose the equation is:
Squaring both the sides:
x + 4 = (x - 2)²
x + 4 = x² - 4x + 4
x² -5x = 0
x = 0 or x = 5
Checking for the solution by plugging in the equation;
3 = 3
2 ≠ -2
The solution x = 0 shows extraneous solution.
Thus, we can check the equation is an extraneous solution or not by finding the solution and plugging it in the equation, to verify it.

All you have to do is try both of the equations by filling in the variables with the choices.
-5 > -3 (2) + 3
-5 > -5 + 3
-5 > -2
-5 > (2) + 2
-5 > 4
So, this does not work.
--------------------------------------------
5 > -3 (-2) + 3
5 > 5 + 3
5 > 8
5 > (-2) + 2
5 > 0
So, this does not work.
-------------------------------------------
5 > -3 (2) + 3
5 > -5 + 3
5 > -2
5 > 2 + 2
5 > 4
So, this works.
-----------------------------
-5 > -3 (-2) + 3
-5 > 5 + 3
-5 > 8
-5 > (-2) + 2
-5 > 0
So, this does not work.
The answer would be C.
I hope this helps!
