Answer is 7/3
The function that represents the relationship between x and y is (y = 4x) and this can be determined by using the given data.
Given :
The value of 'y' varies directly with 'x'.If y = 14 when x = 7/2.The following steps can be used in order to determine the function that represents the relationship between x and y:
Step 1 - According to the given data, the value of 'y' varies directly with 'x'. So, the mathematical expression for this situation is:
[tex]y \; \alpha \; x[/tex]
y = kx --- (1)
Step 2 - It is also given that the value of y = 14 when x = 7/2.
Step 3 - Now, substitute the value of 'y' and 'x' in the above expression.
[tex]\rm 14=\dfrac{7}{2}\times K\\[/tex]
K = 4
Step 4 - Now, substitute the value of K in the expression (1).
y = 4x

Find the unit price of 8 mug for $38.32
Answer: $4.79
Step-by-step explanation:
To find the unit price, we can use a proportion to solve.
[tex]\frac{38.32}{8} =\frac{x}{1}[/tex] [cross multiply]
[tex]8x=38.32[/tex] [divide both sides by 8]
[tex]x=4.79[/tex]
Now, we know that the unit price is $4.79 for each mug.

What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
The value of C = m + 1
The value of B = m + 5
To calculate the value of 2 C + 3 B , substitute the value of B and C in the expression , we get
2 C + 3 B = 2 ( m + 1 ) + 3 ( m + 5 )
= 2 m + 2 + 3 m + 15
= 5 m + 17
Therefore , 2 C + 5 B = 5 m + 17
Hence , the expression 2 C + 3 B equals 5 m + 17 in standard form

what happened before the murder in tell tale heart
Answer:
Be more specific, there was a lot more going down.
Step-by-step explanation: First of all, the narrator had this obsession with the old man. He loved him like family, even if they were mostly close friends. It was the old man's eye that was bothering him. He was mentally ill as the idea is introduced to the reader as they begin the story. With the way he was narrating things, you could tell that he was an unreliable narrator because he's nuts. He went mad almost completely and started to plot the old man's murder. The process took about 3-4 days and nights (From my perspective, I don't have the text available in front of me right now, this is from when I was in 7th grade.) On the 3rd/4th night, he makes a creaking noise. The old man is startled but goes back to sleep. (The narrator moves ever so slowly in his advances each night, and he's careful in his own perspective. Like, just imagine him just looming over the door, ready to pounce. And when he finally got his chance, he rushes at the old man with the axe, old man being scared awake, and decapitated and mutilated into small pieces. The narrator hides the body below the floorboards and the police later arrive, suspecting foul play. After they're satisfied with the search, the narrator breathes a sigh of relief, but then a mental noise starts thumping in his head, and it was the old man's heart beat. (He had heard it as he crept into his room at night during those 3-4 days and nights.) It drove him nuts no matter how much he tried to ignore it. Finally, out of insanity, he rips out the floorboards to reveal the fresh corpse to the horror of the police. The story stops there.
Sally is creating a rectangular quilt and the length is equal to five inches less then the width. The perimeter is 30 inches. What are the dimensions of the quilt
A. Width=5 and length= 10
B. Width=30 and length= 5
C. Width=10 and length =5
D. Width= 5 and length =30
Answer:
It is C
Step-by-step explanation:
c is the only answer that makes sense because 10 is 5 more than 5 as the length so 5 is 5 less than 10.
The dimensions of the quilt are width = 10 and length = 5 which is the correct answer would be option (C).
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
The length of the quilt Sally is making is five inches shorter than the width. The perimeter measures 30 inches which are given in the question.
The perimeter of a rectangle = 2L + 2W
30 = 2L + 2W
L + W = 15
The length is equal to five inches less than the width.
So L = W - 5
Substitute the value of L = W - 5 in the equation L + W = 15
W - 5 + W = 15
2W = 20
W = 10
L = 5
Therefore, the dimensions of the quilt are width = 10 and length = 5.

What you're looking for is to simplyfy the like terms and then isolate the variable. So basically, write everything down and solve it like normal. We know that straight lines are worth 180° and right angles are 90° so that's what's gonna be on one side of the equal sign, and all the other numbers on the other side. Like this:
8.
180 = x + 1 + 3x + 9
180 = 4x + 10
170 = 4x
42.5 = x

Pedro opened a deli in December. The table shows his profits and losses during his first four months of business. Month Profit/Loss ($) December + 724.37 January + 3,912.26 February - 1,051.51 March - 4,023.02 What is the overall profit or loss for the first four months the deli was open?
Answer:
437.90
Step-by-step explanation:
you add the negative numbers together, then the positive numbers. you take the answers from those and subtract them from each other.
The overall loss for the first four months the deli was open is $-437.90.
A firm has a profit when its income is greater than the cost. A loss is recorded when income is less than the total costs. A profit is represented with a positive sign (+) and a loss is represented with a negative sign (-).
In order to determine the overall profit or loss for the first four months add profits and subtract losses.
+ 724.37 + 3,912.26 - 1,051.51 - 4,023.02 = $-437.90.
Costs exceeds revenue so the Deli earns a loss of $437.90.
