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.

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount.
What is the cost in dollars and cents for each video game?
PLZZZZ HELP
Answer:
I would say it's $23.98
Step-by-step explanation:
If you do 100-4.08, you get 95.92 and since there's 4 video games, divide 95.92 by 4 and you get 23.98
Answer:
$23.98 or 2398 cents
Step-by-step explanation:
If the cashier gave $4.08 back, that means that he spent 100-4.08 on the 4 games.
$100 = 4 games + $4.08
4 games = $95.92
$95.92/4 = $23.98

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%

What are the slope and the y-intercept of the linear function that is represented by the equation 8x-2y = 57
5
The slope is 2, and the y-intercept is 4.
5
The slope is 2, and the y-intercept is 4.
5
The slope is 4, and the y-intercept is 2.
5
The slope is 4, and the y-intercept is 2.
Answer:
slope(m)=4 and
y-intercept(c)=-5/2
Step-by-step explanation:
here,8x-2y=5
reducing it into slop intercept form we get,
2y=8x-5
or,y=8/2x+(-5/2)
or,y=4x+(-5/2)
comparing it with y=mx+c we get,
slope(m)=4 and
y-intercept (c)=-5/2
Enter the equation of the line in slope-intercept form. Slope is 1 3 , and (6, 3) is on the line.
Answer:
would it be zero because when you try to find the equation its just 0 so it would be y=3
Step-by-step explanation:
as you can see both the points are at 3. so i would say y=3

Can I get help solve to find X?
==========================================
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.

What is the area of the triangle in the in the diagram?
Answer:
no tengo ni idea
Step-by-step explanation:
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).
The length of the base of the triangle will be given as,
Base = (x₂ - x₁)
The height of the triangle is given as,
Height = (y₂ - 0) or (y₁ - 0)
Height = y₂ or y₁
The area of the triangle will be given as,
A = (1/2) × (x₂ - x₁) × y₁
A = (1/2) y₁(x₂ - x₁)
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
