Answer:
x = 16Step-by-step explanation:
³/₄(x - 12) = 3 {multiply both sides by ⁴/₃}
x - 12 = 4 {add 12 to both sides}
x = 16

What is the situation to 4x^2-25=07
Answer:
x = 2.83
Step-by-step explanation:
Answer:
x=2√2 or x=−2√2
^^Both are correct.^^
Step-by-step explanation:
Let's solve your equation step-by-step.
4x^2−25=7
Step 1: Add 25 to both sides.
4x^2−25+25=7+25
4x^2=32
Step 2: Divide both sides by 4.
4x2 /4 = 32 /4
x^2=8
Step 3: Take square root.
x=±√8
x=2√2 or x=−2√2

Determine if the expression x is a polynomial or not. If it is a
polynomial, state the type and degree of the polynomial.
9514 1404 393
Answer:
x is a polynomial of degree 1
Step-by-step explanation:
"x" is an expression in one variable. The degree of the variable is 1, which is a non-negative integer. So, the expression "x" is a polynomial of degree 1. Because this polynomial has only one term, it is called a monomial. Because the degree is 1, it is a linear polynomial.

Answer:
My summary is on Happy Death Day
Basically there is this girl, she got murdered in the night but before being murdered she spent the entire day being mean and making choices she would later on regret, but when she dies she wakes up again in her room and the same exact things that happened the day the died happened, it was exactly the same. This happened over and over again and she kept dying no matter what she did, it was like a time loop that restarted whenever she was murdered. She had to solve it by killing the one who murdered her or stopping it somehow, she tried everything to avoid being killed. She even got herself sent to jail but still died there, she made a list and tried figuring out who the murderer was. She spent one day being nice to everyone, thinking she had figured out how to stop the murderer because she wanted her day to be great because she thought she wouldnt be killed that night as she thought she knew how to survive. She ate the cupcake her roommate offered her and wasnt murdered that night (the other days she ignored her roommate) Before she went to sleep she said a quote when she was making her Birthday wish (she died on her birthday, hence the name happy death day) "What do you wish for?" "Tomorrow."
"Just...Tomorrow?" "Yeah." She then woke up again in the time loop, and the day repeated. She was confused to why this happened when at the end of the day her roommate offered her the cupcake. She realized the cupcake had poison in it and killed her roommate. But she died again, still in the time loop. She was so confused, all she knew was that her killer wore a mask. Then, after research she figured out it was a mentally ill patient who was killing her. Her best friend (boy friend/guy friend) then sacrificed himself for her taking the hit so she could live, she finally was able to escape the killer. But she realized, if she broke out of the time loop, it would continue so that her guy friend/boy friend was dead. The one who sacrificed himself for her, so she (I don't want this answer to get taken down for describing what she did, but let's say she died on purpose) And woke up again in the time loop. This time she rushed to kill the patient who had been killing her every night in the time loop, and the time loop was broken. That's the summary.

Summary of "Sinister'
so basically it all starts out with a family downsizing their house because of the dad's job. So they move into the house and they find a weird box in the attic, with a few old tapes and a projector, so the dad starts watching the tapes. (on the tapes their are murders of like 5 other families but he doesnt know that.) so then creepy stuff starts happening like first the attic where they found the creepy box keeps opening by itself. then the little girl starts drawing pictures of murders and her with mr.boogie, and the boy keeps waking up with bruises and injuries, and at the end the girl kills the whole family.

Estimate the median time it will take all players to finish this game.
Find the interquartile range for this sample.
Answer:
1148 ; 549.5
Step-by-step explanation:
The ordered data:
457, 548, 866, 952, 976, 1037, 1148, 1235, 1245, 1431, 1486, 1759, 1864
The median value :
1/2 * (n +1)th term
n = 13
1/2 * 14 = 7th term
Median = 1148
The interquartile range :
Q3 - Q1
Q3 = 3/4(n+1)th term
Q3 = 3/4 * 14th term
Q3 = 10.5 th term
Q3 = (10 + 11)th term
Q3 = (1431 +1486) / 2= 1458.5
Q1 = 1/4(n+1)th term
Q1 = 1/4 * 14th term
Q1 = 3.5 th term
Q1 = (3 + 4)th term
Q1 = (866+ 952) / 2= 909
IQR = 1458.5 - 909 = 549.5
Answer:
Median:1054 mins
IQR:751.5

A bookshelf has 36 fiction books and 44 non-fiction books. What percentage of the total books are non-fiction?
Answer:
55% of the total books are non-fiction.
Step-by-step explanation:
There are a total of 80 books, and there are 44 non-fiction books among them.
Divide 44 by 80, then multiply by 100 to get the percentage.
(44/80) × 100 = 55%

A cars gas mileage refers to its rate in miles traveled per gallon of gas. Kara's family is thinking about renting a camper that can travel 3 1/2 miles on 1/3 gallon of gas. Kara wants to know the gas mileage of the camper.
Answer: 10 ¹/₂ miles per gallon
Step-by-step explanation:
The gas mileage of the camper refers to the distance (in miles for this question) that the camper can travel on 1 gallon of gas.
The camper can travel 3¹/₂ miles on ¹/₃ gallons so the mileage is:
= Distance traveled/ Gallons used
= 3¹/₂ ÷ ¹/₃
= 7/2 * 3/1
= 21 / 2
= 10 ¹/₂ miles per gallon

A store made 96 lb of peppermint bark for the holidays. The peppermint bark was split into 3/8 lb portions and boxes. 3/4 of the boxes were sold for $6 each before the holidays. The rest were sold at 2/3 of the pre-holiday price. How much money did the shop receive from the sales of the peppermint bark?
Answer: The shop has received $ 1724 from the sales of the peppermint bark.
Step-by-step explanation:
Given: Total quantity of peppermint bark = 96 lb
Number of [tex]\dfrac38[/tex] portions = [tex]96\div\dfrac38 =96\times\dfrac83=256[/tex]
[tex]\dfrac34[/tex] of boxes = [tex]\dfrac34\times256=[/tex] $192
These were sold for $6 each before the holidays.
i.e. Cost of [tex]\dfrac34[/tex] of boxes = [tex]192\times 6=\$1152[/tex]
2/3 of the pre-holiday price = [tex]\dfrac23\times6=\$9[/tex]
Rest of boxes = 256-192 = 64
Cost of rest of boxes = [tex]9\times64=\$ \ 576[/tex]
Total money received = $1152 + $572
= $ 1724
Hence, the shop has received $ 1724 from the sales of the peppermint bark.

What is an equation of the line that passes through the points (-1, 6) and
(-1, -5)?
Answer:
x = -1
Step-by-step explanation:
(-1 , 6) ; (-1 , -5)
There is no change in x-coordinate values.
So, the is parallel to y-axis
x = -1
Can yall please put the formula as well x
Answer:
x = 10°
Step-by-step explanation:
(3x + 88) + (x + 36) + (2x -4) = 180°
6x + 120 = 180°
6x = 60°
x = 10°

Dominic runs a farm stand that sells peaches and grapes. Yesterday Dominic sold 34 pounds of peaches and 45 pounds of grapes for a total revenue of $192.25. Today he sold 47 pounds of peaches and 16 pounds of grapes for a total revenue of $208. Write a system of equations that could be used to determine the price of each pound of peaches and the price of each pound of grapes. Define the variables that you use to write the system.
Answer:
34x + 45y = 192.25
47x + 16y = 208
Step-by-step explanation:
Let x stand for peaches.
Let y stand for grapes.
Since we know that yesterday he sold 35 pounds of peaches ( x ) and 45 pounds of grapes ( y ) for $192.25, we can create an equation to represent this using two variables; peaches and grapes.
We can do the same thing with the amount of peaches and grapes he sold today. Once we make this equation, we will have two equations to make the system of equations to solve for x and y.
Three times a number, x, increased by four is equal to five times the number, x. Which equation can be used to solve
