Given system of equations:
[tex]\begin{cases}-x+3y=9\\y = \dfrac{2}{3}x\end{cases}[/tex]
Step 1: Substitute the second equation into the first and solve for x.
[tex]\\\implies -x+3\left(\dfrac{2}{3}x\right)=9\ \textsf{[ Multiply. ]}\\\\\implies -x+2x=9\ \textsf{[ Combine like terms. ]}\\\\\implies \boxed{x=9}[/tex]
Step 2: Substitute 9 as the value of x in any equation and solve for y.
[tex]\\\implies-9+3y=9\ \textsf{[ Add 9 to both sides. ]}\\\\\implies -9+9+3y=9+9\\\\\implies 3y=18\ \textsf{[ Divide both sides by 3. ]}\\\\\implies \dfrac{3y}{3}=\dfrac{18}{3}\\\\\implies \boxed{y=6}[/tex]
The solution to the given system of equations is (9, 6).

2)Angle RAT = 32° (Given RAT means that the value is given for the middle alphabet, which means A is 64°. As RAK is half of full angle A, so, 64÷2 )
[Option A]
3)Angle ARS = 116° (180°-64° = 116°)

find four consecutive odd integers such that the sum of twice the smallest and the largest is 11 more than the sum of the middle two integers
Answers
Answer:
x+(2+x)+(4+x)+(6+x)= x+12
2x + 6+x = 3x +6
2+ x + 4+x= 2x + 6
2x + 6 + 11 = 3x+6
2x + 17 = 3x +6
3x-2x = 17-6
x = 11
therefore the four consecutive odd integers are
11, 13, 15 and 17

4cd - 25c^2 - 0.16d^2
= 4cd - (5c)^2 - (0.4d)^2
= -[(5c)^2 -2*5*0.4cd + (0.4d)^2]

Square DEFG with vertices D(0,0).

Answers
Dilation involves changing the size of a square
The vertices of the image are (0,0), (5,10), (15,5) and (10,-5)
How to determine the image of the squareThe vertices of the square are given as:
D(0,0), E(2, 4), F(6,2), and G(4,-2)
The scale factor (k) is given as:
k = 5/2
So, the image of the square is:
[tex]D' = 5/2 * (0,0) = (0,0)[/tex]
[tex]E' = 5/2 * (2, 4) = (5,10)[/tex]
[tex]F' = 5/2 * (6, 2) = (15,5)[/tex]
[tex]G' = 5/2 * (4,-2) = (10,-5)[/tex]
Hence, the vertices of the image are (0,0), (5,10), (15,5) and (10,-5)

Nuka can weave 8.75 cm of strip in 5 minutes
How to determine the length of stripRepresent the ratio with:
Ratio = Length : Time
From the number line, they can weave 7cm of the strip in 4 minutes.
So, we have:
Ratio = 7cm : 4 minutes
Represent the length of strip made in 5 minutes with x.
So, we have:
x : 5 minutes = 7cm : 4 minutes
Remove the common units
x : 5 = 7cm : 4
Express as fraction
[tex]\frac x5 = \frac 74[/tex]
Divide 7 by 4
[tex]\frac x5 = 1.75[/tex]
Multiply through by 5
[tex]x= 8.75[/tex]
Hence, Nuka can weave 8.75 cm of strip in 5 minutes

Celia will be celebrating her 18th birthday. She plans to purchase coin purses as give away gifts A purse costs 50 pesos. How much will the number of coin purses (n) cost if the total cost i represented by A? Write the rule or equation of the situation and give at least 3 ordered pairs.
PLSSS PATULONG PO
Answers
Answer:
Rule: A=50n
Step-by-step explanation:
Because each purse is 50 pesos, and n is the number of purses, and 50n would be the total cost, otherwise known as A.
Our rule is: A=50n
Then we insert 3 values for n, and solve to get the ordered pairs.
n=3 purses, A=3*50=150 dollars
n=4 purses, A=200 dollars
n=5 purses, A=250 dollars

Two numbers add to 336 and the first is 126 bigger than the five times the second. What are the two numbers?
Answers
Answer:
301, 35
Step-by-step explanation:
1st number = x, 2nd = y
x + y = 336
x = 126 + 5y
Then
(126 + 5y) + y = 336
6y = 336 - 126 = 210
y = 210/6 = 35
x = 126 + 5y = 126 + 5*35 = 301
Or x = 336 - 35 = 301
The two numbers are 301 and 35
How much water should be added to 3 gallons of pure alcohol in order to obtain a solution that is 50% alcohol?
Answers
Answer: 3 gallons of water
Step-by-step explanation:
3 gallons of alcohol +3 gallons of water = 6 gallons total
alcohol = 3/6 = 50%
let 3+x=amount of alcohol and water in 15% solution.
Let 3 gallons of alcohol=percentage of alcohol*volume of solution
3=0.15*(3 + x)
3=0.45 + 0.15x
2.55=0.15x
2.55/0.15=x or 17 gallons of water added=x
If you used a random number generator for the numbers from 1 through 20 to play a game, what is the theoretical probability of getting each of these outcomes?
a. A multiple of 3 or a multiple of 7, P(multiple of 3 or multiple of 7)
b. P(even or odd)
c. P(prime or 1)
Answers
Answer: See below
Step-by-step explanation:
Game 1:
20 total numbers
Probability = Multiples of 3 and 7/Total Numbers
P = 8/20
P = 2/5 or 40%
Game 2:
20 total even or odd numbers
Probability = Number of even and odd/Total Numbers
P = 20/20
P = 1 or 100%
Game 3:
8 prime numbers and 1 = 9 total
Probability = Number of prime numbers or 1/Total Numbers
P = 9/20 or 45%
a) The probability of a multiple of 3 or a multiple of 7 is 40%.
b) The probability of even and odd is 100%.
c) The probability of the number being prime is 45%.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Game 1:
20 total numbers
Probability = Multiples of 3 and 7/Total Numbers
P = 8/20
P = 2/5 or 40%
Game 2:
20 total even or odd numbers
Probability = Number of even and odd/Total Numbers
P = 20/20
P = 1 or 100%

They gave us that x is -3 (the first number in an ordered pair is the x).
y = 3^x
y = 3^(-3)
y = 1/(3^3)
