A (I cant say it on here for some reason )water fish tank requires a certain salinity. To reach this requirement, the relationship between gallons of water and pounds of salt needs to be proportional. The relationship can be modeled as a line on the coordinate plane where x represents the number of gallons of water and y represents the number of pounds of salt. If the line passes through the point (5,1.5) , what does that point represent?
Answer: Represents when the equation is at 5 gallons of water 1.5 pounds of salt is needed to have the correct salinity

a girl scout has (5x-12) boxes of cookies and sells (3x+18) of them. Write an expression to represent the amount of boxes she has left. i need help.
Answer:
2x - 30
Step-by-step explanation:
You have to subtract 3x + 18 from 5x - 12:
=> 5x - 12 - ( 3x + 18) = 5x - 12 - 3x - 18 = 5x - 3x - 12 - 18 = 2x - 30
The first step was to apply distributive properties to get rid of the parenthesis, after that the terms were arranged and the like terms combined
Answer = 2x - 30

water drains out of the bathtub at a rate of 5 gallons in 2 1/4 minutes. how much water drains out of the tub each minute?
Answer:
[tex]2~2/9[/tex] gallons per minute
Step-by-step explanation:
If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.
We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!
The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].
So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.
The quantity of water that drains out of the tub each minute is 2.23 gallons.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.
2¹/₄ minuts = 5 gallons
1 minute = 5 / 2¹/₄
1 minute = 5 /2.25
1 minute = 2.23 gallons
Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

Walmart marked up a bottle of nail polish 150% in order to make profit. if Walmart sells the nail polish for $8.75, what was the original cost of the polish?
The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.
Let x be the original price of the polish.
Walmart marked up 150%.
Selling Price = Original Cost + Mark-up
therefore the selling price = x + 150% of x
we know the selling price is $8.75
Therefore, substituting the values:
8.75 = x + 150% of x
convert percentages to decimals:
8.75 = x + 1.5x
combine like terms:
8.75 = 2.5x
divide by 2.5 into both sides:
3.5 = x
use reflexive property:
x = $3.50
Thus, the original price of the nail polish is $3.50.
