let's keep in mind that Profit = Revenue - Costs.
so each guitar costs originally "d" dollars online.
you buy the kits at half price, 50% of the original price, well, the original price is "d", half "d" is just 0.5d, and there's a shipping charge of $4.50. So the Cost to get one kit alone for you is 0.5d + 4.50.
After some work, you resell the kits online for 1.5d + 4.5, so since that's the selling price that is your Revenue for one kit.
[tex]\stackrel{\textit{\Large Profit}}{\stackrel{Revenue}{(1.5d~~ + ~~4.50)}~~ - ~~\stackrel{Costs}{(0.5d~~ + ~~4.50)}}\implies 1.5d+4.5-0.5d-4.5 \\\\\\ 1.5d-0.5d+4.5-4.5\implies 1d\implies d[/tex]

Over a season in a women's basketball league Jackson scored 42 more points than the second-highest scorer, Leslie. Together, Jackson and Leslie scored 1144 points during the season. How many points did each player score
over the course of the season?
First, you know that Jackson (let call her J) scored 42 more points than L (Leslie). What we don't know is how many points L scored so we can use a variable that will be 'x'.
So the equation will be J=42+x.
We also know that the total points is 1,144.
To find out what x is we first subtract 1,144-42. We then get 1,102.
We are now left with 2x and 1,102 so we divide 1,102 by 2 and get 551.
551=x so now we can plug that in.
J = 551 + 42
Jackson scored 593 points and Leslie scored 551 points

Answer:
x is 6 degrees
Step-by-step explanation:
so its 90 degress, how do i know? because it is parrallel to the one with a half square (the 90 degrees) so we equal the angels to 90 because they are equal to 90 (sorry if it sounds confusing, if you want i can still explain more later)
7x + 8x = 90
15x = 90
x = 90/15
x = 6
Answer:
See Below.Explanation:
Both the angles lie inside a right angle, whose total sum is 90 degrees.
Solve:
7(x) + 8(x) = 90°15(x) = 90°x = 6°Each of the angle:
7(x) ⇒ 7(6) = 42°8(x) ⇒ 8(6) = 48°

y = 3x - 10 and y=2x-5
Answer:
x=5
y=5
y = 3x - 10 -----------(1)
y=2x-5------------(2)
Step-by-step explanation:
put the value of y in 2nd equation
y=2x-5
=3x - 10=2x-5
=3x-2x=-5+10
= x=5,
now put the value of x in 1st equation.
y = 3x - 10
=y=3×5-10
=y=15-10
= y=5.
check
put the value of x and y in 1st equation.
y = 3x - 10
x=5,,y=5
=5=3×5-10
= 5=5

Write down a number which is •a multiple of 4. •a factor of 400. •not 4 or 400
Answer:
200
Step-by-step explanation:
4 multiplied by 50 = 200
400 divided by 200 = 2
so it is both a factor of 400, a multiple of 4, and it's neither 4 nor 400 :)

Ben runs 3/4 mile each day.How many Miles Does ben run in 12 days
Answer:
9 miles
Step-by-step explanation:
0.75x12=9
or
75x120=90
90/10=9
If Ben runs 3/4 mile each day than he runs 9 miles in 12 days.
To find out how many miles Ben runs in 12 days
we need to multiply the distance he runs each day (3/4 mile) by the number of days (12).
First, let's convert 3/4 mile to a decimal:
3/4 mile = 0.75 mile
Now, we can calculate the total distance Ben runs in 12 days:
0.75 mile × 12 days
= 9 miles
Therefore, Ben runs 9 miles in 12 days.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inches.
Use pi = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work. (10 points)
Cone:
radius r = 4 inches
height h = 18 inches
volume = πr²h/3 = (3.14)(4²)(18)/3 ≈ 301.44 cm³
Cylinder:
r = 4 inches
h = 3 inches
volume = πr²h = (3.14)(4²)(3) = 904.32 cm³
Volume of cylinder is three times the volume of cone
Is (2, 8) a solution to the equation y = 6x?
Is (2, 8) a solution to the equation y = 6x?
Answer:
No.
Step-by-step explanation:
Substitute 2 for x and 8 for y in y=6x
8 = 6(2) -> 8 = 12
This is false, so (2,8) is not a solution for y=6x

What is the rule and how do you find n? 100 points to answer!
Answer:
n = 17
Rule: y = 2x + 1
Step-by-step explanation:
By inspection of the first two ordered pairs in the given table, it appears that for each 1 unit increase in x, y increases by 2 units.
To check this, write the ordered pairs with 5 ≤ x ≤ 10 using this rule:
(5, 11) (6,13) (7, 15) (8, 17) (9, 19) (10, 21)
As the ordered pair (10, 21) appears in the table, then we can confirm that this is the rule and that it is a linear function.
If y increases by 2 units for every 1 unit increase of x, then the slope of the linear function will be 2.
Using the point-slope form of a linear function: [tex]\sf{y-y_1=m(x-x_1)}[/tex]
(where m is the slope and [tex]\sf(x_1,y_1)[/tex] is a point on the line)
Given:
m = 2[tex]\sf(x_1,y_1)=(5,11)[/tex]Substituting these values into the formula:
[tex]\implies \sf{y-11=2(x-5)}[/tex]
[tex]\implies \sf y=2x+1[/tex]
Therefore, the rule is [tex]\sf y=2x+1[/tex]
To find n, simply substitute x = 8 and y = n into the equation:
[tex]\implies \sf n=2(8)+1=17[/tex]
Therefore, n = 17
Take 2 points and form equation
(5,11)(6,13)Slope:-
m=13-11/6-5=2Equation in point slope form
y-11=2(x-5)y-11=2x-10y=2x+1So
