MONEY PRIZE FOR THE FIRST PERSON TO GET THIS RIGHT AT THE END OF THE PROBLEM LIST METHOD OF ONLINE PAYMENT YOU WANT!
Situation: You love to knit sweaters and you want to start a small business to make money from your talent. You want to do the math first to find out how long it will take for you to make a profit. You must pay a fixed fee of $90.00 to start the company up plus $15.00 for each sweater to pay for the yarn. You want to charge $30.00 for each sweater that you sell.
1. Write an equation for the cost of the company
Choose and define your variables in words:
x:
Equation: y:
2. Write an equation for the money made, INCOME (NOT PROFIT ALL INCOME), selling sweaters
Choose and define your variables in words:
x:
Equation: y:
After you have your equations:
-Find the cost and income when you sell 2 sweaters. (You should have two different answers because you had two different equations one for the INCOME and one for the COST!)
Hints: REMEMBER X is your independent variable so look at the independent number or thing about the problem and write it for x: . Also REMEMBER Y is your dependent variable so whatever your x is y will depend on it if X changes Y also changes look at the problem and ask yourself "What has an effect on what? and "What is effected by what?" This will help you answer the problem.
Answer:
1. y = 90x
x: the amount of companies to start
y: The total amount it will cost.
2. y = 30x
y: the total income
x: the amount of sweaters being sold.
The answer to the last question(I think would be):
cost: $30
income: $60
as:
equation to find cost = y = -15x
equation to find income = y = 30x

After talking with you here are two different options I think you are trying to ask:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are talking about: [tex](\frac{-12}{3}) ^{3}[/tex]
Answer: -62
Explanation:
PEMDAS tells us we need to do the exponent first:
-12³ = (-12)³ = -1728
The parentheses are important so you cube the negative sign as well!
3³ = 27
-1728 / 27 = -62
[tex](\frac{-12}{3}) ^{3}[/tex] simplified is -62
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are talking about (-1[tex]\frac{2}{3}[/tex])³
Answer: -[tex]\frac{125}{27}[/tex]
Explanation:
First, let us turn -1 and two thirds into a mixed number:
Ignoring the negative for now, we can 1 times 3 is 3. 3 plus 2 is 5. 5/3 is 5/3. Adding in the negative we get [tex]-\frac{5}{3}[/tex]
To cube it we must do:
([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])([tex]-\frac{5}{3}[/tex])
3 times 3 (9) times 3 is 27
5 times 5 (25) times 5 is 125
So we have 125/27
For the negative, we have three - - -
Two cancel each other out, and we are left with one (-) so our answer is negative
(-1[tex]\frac{2}{3}[/tex])³ simplifed is -[tex]\frac{125}{27}[/tex]
£20 is divided between Colin, Dan & David so that Colin gets twice as much as Dan, and Dan gets three times as much as David. How much does Colin get?
Answer:
£12Step-by-step explanation:
Let Colin - x, Dan - y, David - z.
We have:
x + y + z = 20x = 2yy = 3zSubstitute and solve for z:
2y + y + z = 203y + z = 203(3z) + z = 2010z = 20z = 2Now find x and y:
y = 3*2 = 6x = 2*6 = 12Answer:
£12
Step-by-step explanation:
Let the David's money be x
If David gets = x
Dan will get = 3x
Colin gets = 3x x 2
= 6x
So, the total money can be write as
[tex]x + 3x + 6x = 10x[/tex]
So, now let's find the amount of money which David have
[tex]10x = 20 \\ \frac{10x}{10} = \frac{20}{10} \\ x = 2[/tex]
So, David will get £2
And now let's find the amount of money which Colin will get
[tex]6x = 6 \times 2 \\ = 12[/tex]
He will get £12
Hope this helps you.

Solve the simultaneous equations.
x + 2y = 9
5x – y = – 10
Answer:
(- 1, 5 )
Step-by-step explanation:
Given the 2 equations
x + 2y = 9 → (1)
5x - y = - 10 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
10x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 1 + 2y = 9 ( add 1 to both sides )
2y = 10 ( divide both sides by 2 )
y = 5
solution is (- 1, 5 )
x + 2y = 9 x + 2y = 9
=====》
5x - y = - 10 (×2) 10x - 2y = - 20
+____________
11x + 0 = - 11
11x = - 11
x = - 1
Thus :
- 1 + 2y = 9
Add both sides 1
2y - 1 + 1 = 9 + 1
2y = 10
Divide both sides by 2
2y ÷ 2 = 10 ÷ 2
y = 5

1 meter wide. How many square meters of sidewalk will he have?
30 m

(Hint: Subtract the area of the garden from the total area covered by
both the garden and the sidewalk. A = A, - A)

Answer:
https://learning-ph.com/math/question7489744
pls check this site
Step-by-step explanation:
Answer:
104 m²
Step-by-step explanation:
There is a 1 m sidewalk around the garden
Then length = 30 + 1 + 1 = 32 m
and width = 20 + 1 + 1 = 22 m
Area = 32 × 22 = 704 m²
Area of garden = 30 × 20 = 600 m²
Area of sidewalk = 704 - 600 = 104 m²
Amy cut 32 feet of chain into pieces that were each 1/4 ft long. How many of these pieces did Amy have after cutting the chain?
Answer:
She will have 8 pieces.Step-by-step explanation:
I divide 32 by 1/4Hope this helps :)
Pls make brainliest :3
And have an amazing day <3
Answer:
128 pieces can be made after cutting the chain
Solution:
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
To find: Number of pieces after cutting the chain
From given,
total length of chain = 32 feet
length of 1 piece = 1/4 feet
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
number of pieces = total length of chain/length of 1 piece
Substituting the values, we get
number of pieces = [tex]\frac{32}{1/4}[/tex]
number of pieces = 32 x 4 =128
Thus 128 pieces can be made after cutting the chain

3. Factor each of the following polynomials using GCF and/or 2 binomials. Show your work. 4 points
A.5x^2 – 2x =
B.x^2 – 12x – 45 =
C.2x^2-x-15
D.9x^2-16
Answer:
See belowStep-by-step explanation:
A
5x² – 2x = x(5x - 2)B
x² – 12x – 45 = x² + 3x - 15x - 45 = x(x + 3) - 15(x + 3) = (x + 3)(x - 15)C
2x² - x - 15 = 2x² + 5x - 6x - 15 = x(2x + 5) - 3(2x + 5) = (2x + 5)(x - 3)D
9x² - 16 = (3x)² - 4² = (3x + 4)(3x - 4)Given :-
A.5x^2 – 2x = B.x^2 – 12x – 45 = C.2x^2-x-15 D.9x^2-16To Find :-
Factorised form into two binomials .Answer :-
A) 5x² - 2x
= x ( 5x -2 )
B) x² - 12x -45
= x² -15x + 3x -45
= x(x -15) +3( x -15)
= (x-15) ( x +3)
C) 2x² - x -15
= 2x² +5x - 6x -15
= x(2x +5) -3(2x +5)
= (x-3)(2x+5)
D) 9x² -16
=(3x)² -4²
= (3x+4)(3x-4) [using a²-b² = (a+b)(a-b) ]
