Answer: In the Instance that she downloads 45 songs, she would pay $40.75. The equation for s songs in one month would be
Money = 7 + s(0.75)
Well, since the time span is a month we can say M is money and n is the amount of months she listens. since this is one month we know N equals 1.
So M = 7n + s(0.75)
7 being the monthly fee, n being the amount of months using the service, s being the amount of songs downloaded, and 0.75 being the cost of every song downloaded.

Solve for the following equation
1/2(2 – 4x) + 2x = 13
Answers
Answer:
no solution
Step-by-step explanation:
1/2(2-4x)+2x=13
We simplify the equation to the form, which is simple to understand
1/2(2-4x)+2x=13
Simplifying:
+ 0.5*(2-4x)+2x=13
Reorder the terms in parentheses
+(+1-2x)+2x=13
Remove unnecessary parentheses
+1-2x+2x=+13
We move all terms containing x to the left and all other terms to the right.
-2x+2x=+13-1
We simplify left and right side of the equation.
0x=+12
0=12
The left and right sides are not equal, therefore there is no solution. This equation is invalid.

If you add 125 to

of a number, the result is 450. Which equation would help find the original number?
Answers
Answer:
2. [tex]\frac{1}{2}x+125=450[/tex]
Step-by-step explanation:
We can use x to mean the number not known. Let's start by using [tex]\frac{1}{2}[/tex] of a number which would be [tex]\frac{1}{2}x[/tex] because the number here is signified by x. Then you would add 125 to that answer which would be shown by [tex]\frac{1}{2}x+125[/tex]. All of it equals 450, so it would be written as [tex]\frac{1}{2}x+125=450[/tex]

Arjun had some chocolates with him. He gave one fourth of them to Arun and one-sixth of them to Varun. Arjun could do so without breaking any chocolate. Which of these could be the number of chocolates Arjun had in the beginning?
Answers
Answer:
See Explanation
Step-by-step explanation:
Given
Arun = ¼
Varun = ⅙
Required
Determine the possible initial number of chocolate
The question requires options to work with which are missing; however, I'll explain how to solve and also list out possible options to make use of.
The question says Arjun gave out fractions of his chocolate without breaking an of them; this means that he gave out whole chocolate (i.e. whole number)
So, to solve this, we multiply the fraction given to Arun and Varun.
Any of the options that results in non decimal integer answers the question.
Take for instance, the options are:
a) 8 b) 15 c) 20 d) 48
Option A: 8
Arun = ¼ * 8 = 2
Varun = ⅙ * 8 = 1.33
Option B: 15
Arun = ¼ * 15 = 3.75
Varun = ⅙ * 15 =2.5
Option C: 20
Arun = ¼ * 20 = 5
Varun = ⅙ * 20 = 3.33
Option D: 48
Arun = ¼ * 48 = 13
Varun = ⅙ * 48 = 8
Option D answers the question because other options resulted in decimals for either Arun or Varun or both of them.
Point Y is between the points X and Z. If XY = 3x – 4, YZ = 2x + 3,
and XZ = 24. What is the numerical length of YZ? Use mathematics
to justify your reasoning.
Answers
Answer: YZ = 13
Point Y is between the points X and Z => XY + YZ = XZ
=> 3x - 4 + 2x + 3 = 24
<=> 5x - 1 = 24
<=> x = (24 + 1) : 5 = 5
with x = 5 => YZ = 2.5 + 3 = 13
Step-by-step explanation:
The length of segment YZ can be found using the segment addition
postulate that specifies the relationship between the segments.
The numerical length of YZ is 13Reasons:
The given location of point Y = Between points X and Z
Length of XY = 3·x - 4
Length of YZ = 2·x + 3
Length of XZ = 24
Required:
The length of YZ
Solution:
XY + YZ = XZ according to segment addition postulate
Therefore;
3·x - 4 + 2·x + 3 = 24
Which gives;
5·x - 1 = 24
5·x = 24 + 1
[tex]x = \dfrac{24 + 1}{5} = 5[/tex]
x = 5
YZ = 2·x + 3
Therefore;
YZ = 2 × 5 + 3 = 13
The numerical length of YZ is 13

Domain: [1, 6]
Range: [1, 7]
General Formulas and Concepts:
Alg I
Domain is the set of x-values that can be inputted into function f(x). Range is the set of y-values that are outputted by function f(x).Step-by-step explanation:
We can find our domain and range from looking from the graph.
Domain
Domain encompasses x-values. According to the graph, the x-values span from 1 to 6. Since both are closed dots, they are included in the domain:
[1, 6] or 1 ≤ x ≤ 6
Range
Range encompasses y-values. According to the graph, the y-values span from 1 to 7. Since both are closed dots, they are included in the range:
[1, 7] or 1 ≤ x ≤ 7
Easy way to remember this: for Domain, look only at the x-axis and for Range, look only for the y-axis.

Zeno jumped 8 meters. Then he jumped half as far again (4 meters). Then he jumped half as far again (2 meters). So after 3 jumps, he was 8+4+2=14 meters from his starting place. 1. Zeno kept jumping half as far again. How far would he be after 4 jumps? 5 jumps? 6 jumps?
Answers
Answer:
1m 0.5m and 0.25m respectively
Answer:
15, 15.5,15.75
Step-by-step explanation:
if Zeno kept jumping half as far then after 4 jumps he would be 15 meters from his starting place.
if Zeno jumped half as far again he would be 15.5 meters from his starting place because 1 divided by 2 is 0.5 and you add that to jumps 1, 2, 3, and 4 and that would be 15.5
if Zeno jumped half as far again he would be 15.75 meters from his starting place because 0,5 divided by 2 is 0.25 and you add that to jumps 1, 2, 3, 4, and 5 and that would be 15.75
The food bill at a restaurant was $56.40. You decide to leave a 15% tip. What is

Answer:$64.86
Step-by-step explanation:
Answer:
$8.46 for tip. The total you paid was $64.86 plus tip.
Step-by-step explanation:
1. Why? First, you need to know the percentage to whole to get to your part. PERCENTAGE: 15% WHOLE: $56.40. (A percent is the percentage of a whole, which is the total.) You need to multiply to get the part.
15% times $56.40
2. How to multiply the percentage to whole.
Put the 15 into a fraction. 15/100, then put the fraction into a demail. (15/100=0.15) Now, multiply.
0.15 x 56.40
(You can add your tip and the bill to get the total of money you spend)

Check all that apply. f(x) > 0 over the interval (−, 3). f(x) ≤ 0 over the interval [0, 2]. f(x) 0 over the interval (–2, 0). f(x) ≥ 0 over the interval [2, ).
Answers
Answer:
2nd, 4th, 5th
Step-by-step explanation:
Options 2, 4 and 5 are correct.
The intervals that satisfies the condition are
f(x)<=0 over the interval [0,2]
f(x)>0 over the interval (-2,0)
f(x)>=0 over the interval [2,∞)
Given : The table with x and f(x) values
Lets analyze the table and check the each option that satisfies f(x) or not .
Look the values of x that is from -3 to 3, the f(x) values are both positive and negative . So f(x)>0 is false over the interval (-∞,3)
From the interval 0 to 2, the f(x) values are 0 and negative .
So , f(x)<=0 over the interval [0,2]
Over the interval (-1,1), f(x) values are both positive and negative
So, f(x)<0 is false over the interval (-1,1)
In the interval (-2,0) , the f(x) is positive.
So , f(x)>0 over the interval (-2,0)
In the interval [2,∞), f(x) is positive
So , f(x)>=0 over the interval [2,∞)
