52.25 x 0.08 = 4.18
So the tax is $4.18, and the total cost is $56.43
Step-by-step explanation:
8x = 1
x = 1/8
So x = 1/8 is the correct answer

Answer:
- 100 mL of 75% solution
- 150 mL of pure alcohol
Step-by-step explanation:
Let x represent the quantity (in mL) of pure alcohol needed for the mix. Then the amount of 75% needed is (250-x). The amount of alcohol in the mixture is ...
1.00x +0.75(250 -x) = 0.90(250)
0.25x +187.5 = 225 . . simplify
0.25x = 37.5 . . . . . . . . subtract 187.5
x = 150 . . . . . . . . . . . . . divide by 0.25
(250 -x) = 100 . . . . mL of 75% solution
You need 100 mL of the 75% solution and 150 mL of pure alcohol to obtain the desired mixture.
To figure it out u plug in ur x value then multiply it by 2 to get ur y value. So if u had a value of 1 for ur x value ur y value would be 2

Answer: = −p97−8p96−256p+1152</h2>
Step-by-step explanation:
<u>Let's simplify step-by-step</u><u>.</u>
8(12−p)(20)−(8+p)(96)−8p96−p96p
Distribute:
=−160p+1920+−96p+−768+−8p96+−p97
<u>Combine Like Terms:</u>
=−160p+1920+−96p+−768+−8p96+−p97
=(−p97)+(−8p96)+(−160p+−96p)+(1920+−768)
=−p97+−8p96+−256p+1152
