the total cost of renting a cotton candy machine for 4 hours is $72. what equation can be used to model the total cost y for renting the cotton candy machine x hours
An equation which can be used to model the total cost (y) for renting the cotton candy machine (x) hours is y = 18x.
What is an equation?An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
What is a system of equations?A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneously.
In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:
Let x represent the number of hours.Let y represent the total cost.Translating the word problem into an equation, we have;
y = 72/4 × x
y = 18x

Jason has $90 to spend. He wants to purchase a bag for $35,one eraser for $10, and three pencils. Each of the pencils costs the same price. This will use up all of Jason's money. Determine the price of a pencil.
Answer:
1 pencil = $15
Step-by-step explanation:
Starting money = 90
Bag price = 35
Eraser price = 10
Price per 1 pencil = X
90 - 35 = 55
$55 after buying the bag.
55 - 10 = 45
$45 after buying the eraser.
45 ÷ 3 = 15
$15 dollars for each pencil.

Step-by-step explanation:
y + 2/5y= y (1 + 2/5)
= 7/5 y
y - 0.32 y (just add)= 1y - 0.32y
= 0.68 y
y - 2/5y
= y (1 - 2/5)
= 3/5 y
y + 0.32 y (just add)
= 1y + 0.32y
= 1.32 y
Answer:
Step-by-step explanation:
y + 2/5y
= y (1 + 2/5)
= 7/5 y
y - 0.32 y (just add)
= 1y - 0.32y
= 0.68 y
y - 2/5y
= y (1 - 2/5)
= 3/5 y
y + 0.32 y (just add)
= 1y + 0.32y
= 1.32 y
One yardstick for measuring how steadily—if slowly—athletic performance has improved is the mile run. In 1958, the local record for the running of a certain distance was 3 minutes, 59.3 seconds, or 239.3 seconds. In the half-century since then, the record has decreased by 0.5 seconds per year.
Answer:
They will hit 180 seconds in 118.6 year
Step-by-step explanation:
Let M be the record for the mile (in seconds)
Let x be the year after 1958
So, x=(year)-19548
We are given that In the half-century since then, the record has decreased by 0.5 seconds per year
So, slope = m = 0.5
Now we will use point slope form
y = mx+c
So, we can express M as,
[tex]M=239.3-0.5 \times x[/tex]
Now we are supposed to find when they will hit 180 seconds
Substitute M = 180 in equation
180=239.3-0.5x
x=118.6
So, they will hit 180 seconds in 118.6 year

What is an equation of the line that passes through the point ( 8 , − 4 ) and is parallel to the line x − 4 y = 12 x−4y=12?
Answer:
as the line is parallel we do not change x-4y what we change is the result x = 8 & y = -4 so the result is 8 - 4 (-4) = 24 so the equation is 24

When you have a percentage you always move two places to the left.
For example 67% , the decimal would be .67 ----> _6_7% the lines are showing the two places you move. Also if you have 157% as a decimal it is 1.57 always move two places to the left no matter how big the percent is!!
