Answer: 7x+46 is most definitely the correct answer , to actually prove you'd have to .
Step-by-step explanation:
simplify step-by-step.
−4x−3(3x−6)+8(2.5x+3.5)
Distribute:
=−4x+(−3)(3x)+(−3)(−6)+(8)(2.5x)+(8)(3.5)
=−4x+−9x+18+20x+28
Combine Like Terms:
=−4x+−9x+18+20x+28
=(−4x+−9x+20x)+(18+28)
=7x+46
Answer:
-4x-3(3x-6)+8(2.5x+3.5)
-4x-9x+18+20x+28
7x+46

You roll a 6-sided die.
What is P(not factor of 35)?
Simplify your answer and write it as a fraction or whole number.
Answer:
[tex]\huge\boxed{\text{P(not factor of 35) = } \frac{2}{3}}[/tex]
Step-by-step explanation:
We can use basic probability to find the probability that this roll is not a factor of 35.
First off, we know that with a six sided die there are 6 possible things we can roll.
1, 2, 3, 4, 5, or 6
Now, what are the factors of 35? The factors of 35 will be any whole number that can be multiplied by another whole number to get 35.
We know [tex]1 \cdot 35 = 35[/tex], so two factors are 1 and 35.We know [tex]5 \cdot 7 = 35[/tex], so two factors are 5 and 7.Therefore, the factors of 35 are 1, 5, 7, 35.
Both 5 and 7 are inside the range of 1-6. So the probability of rolling a side that's a factor of 35 will be [tex]\frac{2}{6} = \frac{1}{3}[/tex] since there are two factors and 6 possible options.
This means, logically, there is a [tex]\frac{4}{6} = \frac{2}{3}[/tex] chance of not rolling a factor of 35.
Hope this helped!

It costs Linus a processing fee of $45 to set up a new cell phone account with AT&T plus $65 per month for the cell phone plan. His sister, Lucy, also wants to use the cell phone to call her friends each month. Lucy agrees to pay Linus $15 towards the processing fee and tells him she will pay $20 per month.
Define a variable.
Write an expression that represents how much Linus will have to pay for the cell phone if Lucy contributes.
Determine how much Linus will pay if he has the cell phone for 6 months.
Step-by-step explanation:
Let x represent the number of months for the cell phone plan.
Since Lucy is contributing, Linus does not have to pay the full cost.
Instead Linus will have to pay:
($45 + $65x) - ($15 + $20x)
= $30 + $45x.
If x = 6,
Linus will pay $30 + $45(6) = $300.

What is the probability a sample of 66 test takers will provide a sample mean test score within 10 points of the population mean of 533 on the Evidence-based Reading and Writing part of the test?
This question is incomplete, the complete question is;
A certain organization reported the following scores for two parts of the scholastic Aptitude test ( SAT)
Evidence-based Reading and writing : 533
Mathematics : 527
Assume the population standard deviation for each part is σ = 100.
What is the probability a sample of 66 test takers will provide a sample mean test score within 10 points of the population mean of 533 on the Evidence-based Reading and Writing part of the test?
Answer: the required probability is 0.582
Step-by-step explanation:
Given that;
Population mean = 533
sample size n = 66
population standard deviation σ = 100
σ of x bar = 100/√66 = 12.3091
Normal distribution with mean 533 and SD of 12.3091
P( 523 <x< 543 )
Z = 10 / 12.3091
Z = 0.8124, -0.8124
P( z < 0 0.8124) - P( z < -0.8124) { from table}
⇒ 0.7910 - 0.2090
= 0.582
Therefore, the required probability is 0.582

Calculating the slope is simple
First, pick two points on the line
Next, see how far the second point is from the first point in the y direction only (the rise)
Next, see how far the second point is from the first point in the x direction only (the run)
Finally, divide the rise by the run
Q1:
rise 1
run 2

A painting is 23 inches high and 11 inches wide. What is the diagonal length across the painting?
Answer:
the diagonal length is 25.50
Step-by-step explanation:
The computation of the diagonal length across the painting is as follows:
As we know know that
The Diagonal length would be
= [tex]\sqrt{w^2 + l^2}[/tex]
where
w = width
l = length
So, the diagonal length is
[tex]= \sqrt{23^2 + 11^2}\\\\= \sqrt{529 }+ 121} \\\\= \sqrt{650}[/tex]
Hence, the diagonal length is 25.50
Diet cola was on sale last week; it cost $10 for every 4 packs of cola. How much do 2 packs of cola cost?
Answer:
2 pack of cola would cost $5.
Step-by-step explanation:
the reason for this being is that
4 packs of cola = $10
2 is half of 4
5 is half of 10
$5<====
Answer:
I would say 5$
Step-by-step explanation:
You are going from 4 packs to 2 packs (so you are dividing by 2). So if you divide 10$ by 2 you get 5$

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Paul has scored 75, 80, and 91 on the first three. What range of scores on the fourth test will give Paul a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Answer:
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
Step-by-step explanation:
The average is given by the sum of all scores divided by the number of scores.
In this question:
Sum of all scores: 75 + 80 + 91 + x = 246 + x
Number of tests : 4
Grade of 70:
[tex]\frac{246 + x}{4} = 70[/tex]
[tex]246 + x = 280[/tex]
[tex]x = 280 - 246[/tex]
[tex]x = 34[/tex]
Grade of 79:
[tex]\frac{246 + x}{4} = 79[/tex]
[tex]246 + x = 316[/tex]
[tex]x = 316 - 246[/tex]
[tex]x = 70[/tex]
Scores between 34 and 70 on the fourth test will give Paul a C for the semester.
On their most recent 8-mile training run, Pepe averaged a speed of
I of a mile in 4.5 minutes, while Paula averaged of a mile in 7.5
minutes.
How many minutes did it take the faster runner to finish the 8 mile
run?
Answer:
36 minutes
Step-by-step explanation:
Given that:
The length of run = 8 miles
Average speed of Pepe = 4.5 minutes per minute
Average speed of Paula = 7.5 minutes per minute
To find:
Minutes taken by the faster runner to finish the 8 mile run?
Solution:
First of all, let us have a look at the relation between Time and Speed.
[tex]Speed = \dfrac{Distance}{Time}[/tex]
If the distance is a constant, then
[tex]Speed \propto \dfrac{1}{Time}[/tex]
i.e. Speed is inversely proportional to time.
That means faster runner will take smaller amount of time.
So, faster runner is Pepe who is taking lesser time.
Time taken to complete 1 mile = 4.5 minutes
Time taken to complete 8 miles = 4.5 [tex]\times[/tex] 8 minutes = 36 minutes
So, the faster runner i.e. Pepe takes 36 minutes.
