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

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

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

[tex]Solve : 3x = \frac{x}{2} - 5 \\ [/tex]
Correct answer will be mark as brainliest.
Answer:
-2
Step-by-step explanation:
As per the provided information in the given question, we have a linear equation. We have to find the value of x.
Here, we'll use transposition method to solve this linear equation.Basically, transposition method is used to solve a linear equation in one variable containing constants and variables. We just transpose the values from RHS to LHS by changing its arithmetic operators. In this way, we solve for the unknown value. During transposing the values, ( + ) changes to ( – ) and vice-versa ; ( × ) changes to ( ÷ ) and vice-versa.
Now, coming back to the question. We have,
[tex]\longmapsto \rm { 3x = \dfrac{x}{2}- 5} \\ [/tex]
Taking the LCM in RHS and performing subtraction.
[tex]\longmapsto \rm { 3x = \dfrac{x - 10}{2}} \\ [/tex]
Transposing 2 from RHS to LHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { 3x \times 2 = x - 10} \\ [/tex]
Performing multiplication in LHS.
[tex]\longmapsto \rm { 6x = x - 10} \\ [/tex]
Transposing x from RHS to LHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { 6x - x = - 10} \\ [/tex]
Performing subtraction of the terms in LHS.
[tex]\longmapsto \rm { 5x = - 10} \\ [/tex]
Transposing 5 from LHS to RHS. Its arithmetic operator will get changed.
[tex]\longmapsto \rm { x = \cancel{\dfrac{- 10}{5}}} \\ [/tex]
Dividing –10 by 5.
[tex]\longmapsto \underline{\boxed{\bf { x = - 2}}} \; \bigstar \\ [/tex]
Therefore, the value of x is –2.
how to find the domain and range of y=|x| ?
£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.

Answer:
41. D, 42. B, 43. AStep-by-step explanation:
Sides are 120 m, 170 m, 250 m
41.S is the semi-perimeter and is equal to:
s = (a + b + c)/2 = (120 + 170 + 250)/2 = 270 mCorrect choice is D
42.The area is easy to calculate using the Heron's formula, since we have all three side lengths known.
Correct choice is B
43.Perimeter is:
P = a + b + c = 120 + 170 + 250 = 540 mCorrect choice is A

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]

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) ]
