Answer:
x = 30
General Formulas and Concepts:
<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
8x - 3(2x - 4) = 3(x - 6)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 8x - 6x + 12 = 3x - 18
- Combine like terms: 2x + 12 = 3x - 18
- Subtract 2x on both sides: 12 = x - 18
- Add 18 to both sides: 30 = x
- Rewrite: x = 30
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 8(30) - 3(2(30) - 4) = 3(30 - 6)
- Multiply: 240 - 3(60 - 4) = 3(30 - 6)
- Subtract: 240 - 3(56) = 3(24)
- Multiply: 240 - 168 = 72
- Subtract: 72 = 72
The mean is the average of a set of numbers. You add all of your numbers together (example = 1+5+3= 9), then you divide the answer by the number of numbers you have used ( 9 divided by 3 = 3) so the mean is 3
I think it’s 17/20. i hope i helped
I am sorry, but nobody can help until you put the question. Assuming it is Algebra, I can write this as function which would be y = 3x + 14.99 . Also, x has to be greather than zero because you cannot undownload a movie. y can also be something like f (m). m means the movies you downloaded. So it could also be f = 3m + 14.99 . If you want to graph it, I could do it for you.
Answer:
x = 3 and x = -2
Step-by-step explanation:
The given equation is :
We need to solve the given equation.
We can solve it using Completing the Square method.
We take two numbers such that their product is -6 and sum is -1.
So,
so, the values of x are 3 and -2.
