Answer:
D. None of the choices are correct.
Step-by-step explanation:
If <em>B</em> is the midpoint of AC, then that means that AB is congruent to BC. Because this is true, you can set 8x + 4 and 10x - 8 equal.
8x + 4 = 10x - 8
Now just solve for x. Subtract 8x from both sides and add 8 to both sides.
4 = 2x - 8
12 = 2x
Then divide by 2.
6 = x
Another way to do this problem is to set up the same equation, but instead of solving it, plug in answer choices A, B, and C independently of each other. Then simplify to see if those are right. You'll find out that none of them are.
Answer:
y= 1/4 x-62+1
Step-by-step explanation:
Jessica purchased a DVD that was on sale for 12% off.
The sales tax in her county is 3%.
Let, y represent the original price of the DVD.
We can simply solve this mathematical problem by using the following mathematical process.
Here, we will form an algebraic expression, according to the given data.
So,
The original price of the DVD = y
Discount on the original price :
y * 12/100
=3y/25
Price after discount :
y - 3y/25
=25y - 3y/25
=22y/25
Sales tax amount :
22y/25 * 3/100
11y/25 * 3/50
=33y/1250
Final price including the sales tax :
22y/25 + 33y/1250
1100y + 33y/1250
1133y/1250
(This will be considered as the final result.)

Answer:
p = 10.44
Step-by-step explanation:
There is no solution. If the question was 81p / 9 = 94, it could be done.
The way it is written the ps cancel out and you get 9 = 94 which is impossible.
But let's assume you meant
81p / 9 = 94
Then you get 9p = 94 Divide both sides by 9
81p/9 = 94
9p = 94 Divide both sides by 9
9p/9 = 94/9
p = 10.44
12 = 3x - 15
12 + 15 = 3x
27 = 3x
27/3 = x
9 = x
x = 9
