Answer:
k = 15
Step-by-step explanation:
For a proportional relationship to exist then for both points
k = [tex]\frac{y}{x}[/tex] ← k is the constant of proportion, that is
[tex]\frac{5}{3}[/tex] = [tex]\frac{k}{9}[/tex] ( cross- multiply )
3k = 45 ( divide both sides by 3 )
k = 15
James wants to buy some CDs that cost $14 each and a DVD that costs $23. He has $65. Write an equation (in the Show your work area) and solve to find how many CDs he can buy. Include "CD" in your answer.
Answer:
3
Step-by-step explanation:
65-23= 42
42/14= 3
Answer:
14x+23 =65 x=3CDs
Step-by-step explanation:
So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.
To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.
I hope this helps.

==========================================
Explanation:
The same tickmarks on each side of the triangle tells us that all three sides are the same length. This triangle is equilateral.
All equilateral triangles have each of their three angles at 60 degrees (they are considered equiangular). This is because 60+60+60 = 180.
Set 2x+32 equal to 60 and solve for x
2x+32 = 60
2x = 60-32
2x = 28
x = 28/2
x = 14
As a check,
2x+32 = 2*14+32 = 28+32 = 60
which helps confirm the answer.

Suzie bought a sweater at the sale price of $25. The original cost of the sweater was $40. What percent represents the discount that Suzie received when buying the sweater? A.15%, B.37.5% C.60% D.62.5%
Answer:
B.37.5%
Step-by-step explanation:
Step one:
given
The sale price of $25
The original cost of the sweater was $40
Required:
The percent discount
Step two:
% discount= change in price/original price *100
%discount = 40-25/40 *100
% discount= 15/40*100
% discount = 0.375*100
% discount =37.5%

The sides of two similar trapezoids are in a ratio of 1:3. The area of the smaller trapezoid is 12 squared inches. Find the area of the larger trapezoid
Answer:
108 sq in.
Step-by-step explanation:
The ratio of the areas is the square of the ratio of the sides.
Side ratio 1:3
Area ratio 1:9
The side of the larger trapezoid is 3 times the side of the smaller trapezoid.
The area of the larger trapezoid is 9 times the area of the smaller trapezoid.
9 * 12 sq in. = 108 sq in.

The table below contains data on how many pages were read for homework in Mr. Kaplinsky's third period. The equation of the line of best fit for the data is y = 28.3x + 4.8. Which two statements accurately describe the slope for the line of best fit? About 28.3 pages were read each hour. The most that any student can read is 4.8 pages per hour. For each additional hour spent reading, approximately 4.8 additional pages can be read. If a student starts reading faster, they will read 28.3 more pages in each additional hour they read. If a student reads for 1 hour longer than another person, they will have read approximately 28.3 more pages.
Answer:
28.3
