Answer:
There is 20 dollars and the cost is 1.29. You need to have more money than the cost
To see if he can buy Y many songs
20 > 1.29 x Y
If you want how many songs
20/1.29=amount of songs
20/1.29 = 15.5
You round down because he cannot afford the full 16th song but can afford the 15th song fully so he can buy 15 songs
Hope this helps. If you have any questions you can ask
Step-by-step explanation:
Answer:
Sample response: If x represents the number of downloads, you can write the inequality 1.29x ≤ 20. Solving the inequality, you find that x is less than or equal to about 15.5. Since he can’t download part of a song, Joseph can download 15 or fewer songs.

Please select the best answer from the choices provided

Answer:
15x + 14y + 36 = 0
Step-by-step explanation:
As we travel from the point (-8, 6) to the point (6, - 9), the increase in x (the "run") is 14 and that in y (the "rise") is -15. Thus, the slope of the line segment connecting these two points is m = rise / run = -15 / 14.
Let's use the point (6, -9) and the slope m = -15/14 to write the equation of this line:
Adapting y = mx + b, we get:
-9 = (-15/14)(6) + b, or
-9 = -45/7 + b, which yields b = 45/7 - 9, or b = 45/7 - 63/7, or b = -18/7
Then the equation is y = (-15/14)x - 18/7
We must put this into "standard form." Multiplying all three terms by 14 to clear the fractions out, we get:
14y = -15x - 36, or (in standard form):
15x + 14y + 36 = 0

5x-2y=305x−2y=30
Complete the missing value in the solution to the equation.
(8, )
Answer:
5
Step-by-step explanation:
For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.
5x -2y= 30
When x=8,
5(8) -2y= 30
40 -2y= 30
40 -30= 2y (bring constant to 1 side)
2y= 10 (simplify)
y= 10 ÷2
y=5
Thus the missing value is 5.
Two angles of a quadrilateral measure 140° and 80°. The other two angles are in a
ratio of 3:4. What is the value of x? What are the measures of those two angles?
Answer:
Step-by-step explanation :
Ratio = 3x : 4x
Sum of angle of a quadrilateral = 360Therefore, 140+80+3x+4x = 360220+7x = 3607x = 360-220x= 140/7x=203x= 3×20=604x=4×20=80Answer:
60 and 80 degrees.
Step-by-step explanation:
The other 2 angles have the sum : 360 - (140 + 80)
= 360 - 220
= 140. (because the 4 angles in a quadrilateral add up to 360).
As the other 2 angles are in the ratio 3:4 one angle = 3/7 of 140 and the other is 4/7 of 140.
This is equal to 3 *20 and 4 * 20 = 60 and 80 degrees.

A multi level parking lot has 6 levels and there are total of 1,327 parking spots.
1.
There are 162 parking spots on the first level. The rest of the parking spots are
distributed equally on the other 5 levels. How many parking spots are there on
the top level?
2.
There are 12 spots close to the 3 elevators reserved for drivers with disabilities
on each level. How many parking spots are reserved for drivers with disability
altogether?
3.
Other than the spots reserved for drivers with disability, there are 285 parking
spots for monthly rental and the rest are for hourly parking. How many spots are
there for hourly parking?
4.
The daily parking rate is $30. If Jack parks his car for 5 days a week and 4 weeks
in a month, how much does he pay for parking in a year?
Answer: (1) There are 233 parking spots on the top level
(2) There are 72 parking spots reserved for drivers with disabilities
(3) There are 970 spots for hourly parking
(4) He would spend $7200 for parking in a year
Step-by-step explanation: In the first instance, there is a total of 1327 parking spots altogether allocated into various categories.
(1) There are 6 levels in all, and the first level has 162 parking spots. herefore the remaining 5 levels would have 1165 parking spots left as shown below;
Remainder = 1327 - 162
Remainder = 1165
If however the remaining 1165 parking spots are distributed equally among the other 5 levels, then each level would have 233 parking spots each as shown below;
Five levels = 1165
Each level = 1165/5
Each level = 233
Therefore the top level has 233 parking spots
(2) On each level (out of all 6 levels), there are 12 spots reserved for drivers with disability. Therefore at all parking levels you would have 72 spots as shown;
Reserved spot per level = 12
Reserved spot for 6 levels = 12 * 6
Reserved spot for 6 levels = 72
Therefore there are 72 spots reserved for driver with disability
(3) Other than the spots reserved for drivers with disability (72), there are 285 parking spots for monthly rental. The rest are for hourly parking, and this is calculated as shown;
Hourly parking + monthly rental + reserved parking = 1327
Hourly parking + 285 + 72 = 1327
Hourly parking + 357 = 1327
Hourly parking = 1327 - 357
Hourly parking = 970
Therefore there are 970 spots available for hourly parking.
(4) If the daily parking rate is $30, and Jack parks his car for 5 days in a week, then he would spend
30 * 5 = 150
If he parks for 4 weeks in a month, then he would spend
150 * 4 = 600
Therefore to pay for parking in a year (12 months) he would spend
600 * 12 = 7200
Therefore he would spend $7,200 for parking in a year

Answer:
D. For a ratio of 3:2, divide AB into 5 equal parts. Each equal part is 2 units, so the point that divides AB into a 3:2 ratio is 2.
Step-by-step explanation:
The complete question is:
Point A is at –4 and point B is at 6. Which describes one way to find the point that divides AB into a 3:2 ratio?
In a 3:2 ratio there are 3 + 2 = 5 equal parts.The distance between points A and B is: 6 - (-4) = 6 + 4 = 10 units.Each equal part is 10/5 = 2 units.Point 2 is at 2 - (-4) = 6 units from -4Point 2 is at 6 - 2 = 4 units from 6Ratio 6:4 is equivalent to ratio 3:2

Two angle of a quadrilateral measure 140 and 80. the other two angels are in a ratio of 3:4. what is the value of x? what are the measures of those two angles?
Answer:
60° and 80°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Given 2 angles in ratio 3 : 4 = 3x : 4x ( x is a multiplier )
Sum the 4 angles and equate to 360
140 + 80 + 3x + 4x = 360, that is
220 + 7x = 360 ( subtract 220 from both sides )
7x = 140 ( divide both sides by 7 )
x = 20
Thus
3x = 3 × 20 = 60° and 4x = 4 × 20 = 80°
