Answer:
A. The constant ratio of y/x is 12/5
Step-by-step explanation:
The ratio of y to x is constant which is 12/5. Hence option A is the correct option.
What is a constant?
The term "constant" has several meanings in mathematics. When used as a noun, it can have any of the following two meanings: a constant, clearly defined number or another immutable mathematical object.
Given table is
x y
5/6 2
25/6 10
125/6 50
625/6 250
When x = 5/6 and y = 2:
x/y = (5/6)/2 = 5/12
∴y/x = 5/12
When x = 25/6 and y = 10:
x/y = (25/6)/10 = 25/60 = 5/12
∴y/x = 5/12
When x = 125/6 and y = 50:
x/y = (125/6)/50 = 125/300 = 5/12
∴y/x = 5/12
When x = 625/6 and y = 250:
x/y = (625/6)/250 = 625/1800 = 5/12
∴y/x = 5/12

Answer:
4(x-1)+9=17
Step-by-step explanation:
3(-2x+1) + 5 = 3x-4-5x
expand
-6x + 3 + 5 = 3x-4-5x
-6x + 8 = -2x - 4
add 2x to both sides to put all x values + coefficients on one side
-4x + 8 = -4
subtract 8 from both sides to isolate x and its coefficient
-4x = -12
divide both sides by -4 to isolate x
x = 3
plug x=3 into each option to see if it works
1. 5(3+3)-4 = 30-4 = 26 != 10
2. 2(3+1) = 8 != 4
3. 4(3-1)+9 = 17 = 17

What is the fewest number of people surveyed if exactly 93.6% of people completed a survey?
Use the whole numbers 0 through 9, at most one time, to fill in the boxes to create an accurate
number line.
Answers
Answer:
Step-by-step explanation:
7
the percentage of people that finished the survey is 93.6%, given.
this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.
you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.
p = 117/125.
the fraction can’t be reduced any further, so that’s your answer.

Charlie bought pound of American cheese and pound of Swiss cheese. Josh bought pound of cheddar cheese and pound of jack cheese. Josh says that they bought the same amount of cheese. Is he correct? Explain.
Answers
Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.
Step-by-step explanation: It's hard to say because you would need the weight of the cheese.

y equals one third x

Answers
Answer:So let's start by guesstimating the slopes:
the green line has a slope close to -x, but more negative than that, possibly -2; the pink line has a slope close to +x, but higher towards +2.
Next let's look at the solution: the two lines intersect at the point (1, -1).
**you could just simple plug that x (1) into all the equations, but let's rule out answers anyway. ;)
A) is incorrect because the slopes of -1 and +1 are off from out predicted -2 and +2
B) is incorrect because of a similar reason, the slopes of +3 and +1 don't make any sense
C) Ooh, we do have a +2 and -2 for the slopes, and... violà! plug in 1 for the x's and we get -1 for the y in both equations
D) slopes are closer than in A and B, but plugging in 1 doesn't get us -1
So the correct answer is:

Because all of the equations are true, we know the relationship between the number of bags of screws and the price is proportional.
Answer: proportional

if you divide 10 by 2 you get 5.
since 4 times 5 is 20 and 7 times 5 is 35

What is the frequency?
The number of times a specific value appears in the data is its frequency (f). A variable's distribution is its frequency pattern, or the collection of all conceivable values and the frequencies corresponding to those values. Frequency tables or charts are used to represent frequency distributions.

The frequency of group 1 is (4+7) = 11
The frequency of group 2 is (3+9) = 12
The frequency of group 3 is (11+8) = 19.
The relative frequency is the ratio between the number of times an outcome value appears in the set of all outcomes and the total number of outcomes.

You collect $20.92 for selling 4 video games and 2 cellphones on a website. Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website. How much do you collect for each video game?
Answers
Answer: D
Step-by-step explanation:
x = video games
y = cellphone
Equation: (1) 4x + 2y = 20.92
(2) 4x + 3y = 23.44
_________________
y = 2.52
4x + 2y = 20.92
4x + 2(2.52) = 20.92
4x = 20.92 - [ 2(2.52) ]
4x = 15.88
x = 3.97
Amount collected for each video game is option D. $3.97.
What are Linear Equations?Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.
Let x be the amount got for selling one video game and y be the amount got for selling cellphones.
You collect $20.92 for selling 4 video games and 2 cellphones on a website.
4x + 2y = 20.92
4x = 20.92 - 2y
Your friend collects $23.44 for selling 4 video games and 3 cellphones on the website.
4x + 3y = 23.44
4x = 23.44 - 3y
Equating both the equations,
20.92 - 2y = 23.44 - 3y
Simplifying,
y = 2.52
Substituting y = 2.52 in 4x + 2y = 20.92,
4x = 15.88
x = 3.97
Hence the amount for selling one video game is $3.97.

Kado spent 1 2/3 hours painting a fence. Then he spent 4/5 of an hour walking his dog. How much longer did he spend painting than walking? Orleans chose C as the correct answer.How did she get that answer?
Answers
Answer: B, 13/15
Step-by-step explanation: If you multiply both to 15, you will get 1 10/15 and 12/15 if you then subtract the two of them you will be left with
13/15.
Orleans might have got the answer from subtracting wrong or adding them together.
Hope this helps! :)
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.
To find out how much longer Kado spent painting than walking his dog, we need to calculate the difference between the time he spent painting and the time he spent walking his dog.
Kado spent 1 2/3 hours painting the fence.
He spent 4/5 of an hour walking his dog.
To make the calculation easier, let's convert 1 2/3 hours into an improper fraction:
1 2/3 = (3*1 + 2)/3 = 5/3 hours
Now, the time difference is:
Time spent painting - Time spent walking
= (5/3) - (4/5)
To subtract fractions, we need to find a common denominator, which in this case is 15 (the least common multiple of 3 and 5):
= (5/3)(5/5) - (4/5)(3/3)
= 25/15 - 12/15
Now, we can subtract the fractions:
= (25 - 12)/15
= 13/15 hours
Orleans must have chosen C as the correct answer, which is 13/15 hours. This means that Kado spent 13/15 hours longer painting the fence than walking his dog.

Carter wants to ride his bicycle 28.7 miles this week. He has already ridden 17 miles. If he rides for 3 more days, write and solve an equation which can be used to determine mm, the average number of miles he would have to ride each day to meet his goal.
Answers
Answer: Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal.
Step-by-step explanation:
Finding the answer to this problem isn't too complicated, and all we have to do is make and solve an equation. First, we know how many miles Carter wants to ride his bicycle (this is what our equation will be equal to), and how many miles he's completed already (we add that to how many he has to do daily). We also know how many days he has left to complete this goal (multiply the number he has to do daily by three).
All we have to do now is construct a basic equation:
17 + 3x = 28.7
Let's move the 17 over to the other side of the equation. To do that, subtract 17 from both sides.
3x = 28.7 - 17
3x = 11.7
This gives us the amount of miles Carter still has to ride - in total. To find out how many miles he has to ride daily, we just divide 3 from both sides.
3x/3 = 11.7/3
x = 3.9 (miles - don't forget the units!)
Carter will have to ride 3.9 miles on his bicycle every day in order to achieve his goal. Hope this helps!
