Answers
Answer:
Step-by-step explanation:
0.1315 with a bar over all numbers means that the pattern of digits under the bar repeats without end. So the number is 0.1315131513151315131513151315....... etc
There is a formula to kind of simply this but I do not think that is what you are asking for.
Answer:
[tex]\overline{0.1315}=\frac{1315}{9999}[/tex]
Step-by-step explanation:
The trick is that because there are 4 digits being repeated infinitely, then this is equivalent to 1315/9999 because of the four 9s.

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!

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.

Which graph shows the solution to the system of linear equations?
y equals one third x
x + 3y = −6
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:
C) y = 2x - 3 and y = −2x + 1

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.

Multiply .15 * 245 =$36.75 ok that’s the first discount!
Second discount is 10% so turn 10% into a decimal (by dividing your percentage by 100) = .10
