Answer:
x=2
Step-by-step explanation:
We first distribute this. So we have 15x-10 = 10 + 6 +2x.
Then we move the variable to one side and have 13x= 10+10+6
Simplify to get 13x = 26.
x=2

what is the quotient of 6 1/4 ÷ (-5/8)
Answer: -10
Step-by-step explanation:
1. Convert 6 1/4 to an improper fraction
25/4
2. Find the quotient using the keep, change, flip method
- Keep the first fraction (25/4)
- Change the division sign to a multiplication sign
- Flip the second fraction (i.e. find the reciprocal)
-5/8 -> -8/5
3. Multiply and solve by multiplying the numerators and denominators together respectively
25/4 * -8/5
25*-8 = -200
4*5 = 20
-200/20 = -10

Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper. The scatter plot shows the data he gathered and the line of best fit.
The equation of the line of best fit is y = 70.28x + 425.77.
Based on the line of best fit, approximately how many minutes would a student who consults 3 books spend on a research paper?

The student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]
We have:
Kevin gathered data from his classmates about the number of books they consulted and the total time they spent on a research paper.
The line of best fit is:
y = 70.28x + 425.77
Plug x = 3 in the line of best fit:
y = 70.28(3) + 425.77
y = 21.084 + 425.77
y = 636.61 minutes ≈ 637 minutes
Thus, the student who consults 3 books spends 637 minutes on a research paper based on the line of best fit if the equation of the line of best fit is y = 70.28x + 425.77 option (D) is correct.

graph y=3/4x-4 ....……………
The required graph is shown below that represents equation y = (3/4)x - 4.
The equation y = (3/4)x - 4 represents a linear function in slope-intercept form, where the coefficient of x is the slope of the line and the constant term (-4) is the y-intercept.
To graph the equation y = (3/4)x - 4, follow these steps:
Start by plotting the point (0, -4) on the y-axis. This is the point where the line intersects the y-axis.
Since the slope is 3/4, it means that for every 4 units moved to the right along the x-axis, the corresponding y-value moves up 3 units.
From the y-intercept (0, -4), move 4 units to the right and then 3 units up to find another point. This gives us the point (4, -1).
The two points (0, -4) and (4, -1), draw a straight line passing through both points. This line represents the graph of the equation y = (3/4)x - 4.

The obriens are buying new windows for their house. The company installs the new windows for 2100 the total cost for buying the windows and having them installed is 5323.50 of the o'briens pay 230.25 per window how many windows did they buy
Answer:
14
Step-by-step explanation:
Given that:
Cost of purchase and installation = 5323.50
Cost per window = 230.25
Cost of installation = 2100
Hence,
Total purchase cost of windows alone :
5323.50 - 2100 = 3,223.50
Therefore, the number of windows purchased is :
(Total purchase cost of windows alone / price per window)
(3,223.50 / 230.25)
= 14
Hence, 14 windows was purchased

A)Multiply every term in the bottom equation by 3.
B) Multiply every term of the bottom equation by 2.
C) Multiply every term of the bottom equation by -3.
D Multiply every term of the top equation by 2, and every term of the bottom equation by 4.
Answer:
I think that the answer would be C because you have to multiply the term at the top. This would mean you would not do C. Sorry if this is wrong. At least you have your eliminating process now. lol so doing C is out of the box, which makes C your answer.

On a game show, Celine is given the digits from 1 to 6 and has to use them to fill in a row with 2 spots. If the number formed is the correct price of the item displayed, she wins the item. Given that each digit can be used only once, how many 2-digit prices are possible?
Answer:
30 Two digits prices are possible.
Step-by-step explanation:
Celine was given numbers from 1 to 6
so the possible numbers are 1, 2, 3, 4, 5, 6
And we need to make a two digit number using these digits by using them only once
Using the box method of permutation
We have 6 possibilities on the tenth place of the two digit numberOn the One's place we will have 5 choices of numbers as one among these six given digits is used on the tenth place (Non repeating)So we will have total permutations = 6*5 = 30
Therefore 30 Two digits prices are possible.

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t .
Write an inequality that can be used to represent the cost of a pizza that is at most $12.
What is the most number of toppings that a pizza can have and still be at most $12?
Step-by-step explanation:
$9.99 + $0.35t <= $12
$0.35t <= $2.01
t <= 5.74
The most number of toppings would be 5.
Answer:
9.99 + 0.35t ≤ 12
5 toppings
Step-by-step explanation:
First part of question:
9.99 + 0.35t ≤ 12
"At most" means you use ≤.
Second part of question:
Take the inequality and solve for t:
9.99 + 0.35t ≤ 12
0.35t ≤ 2.01
t ≤ 5.74
So, the most number of toppings that a pizza can have and still be at most $12 is 5 toppings. You have to round down 5.74 to 5 otherwise the cost will exceed $12.
