solve
with elimination and substitution method
Answer:
x=1, y=3
Step-by-step explanation:
using sublimation method
y-3x=0 ....eqn(1)
2y+5x=11....eqn(2)
from eqn 1
y-3x=0
y=3x
substitute y=3x into eqn 2
2y+5x=11
2(3x)+5x=11
6x+5x=11
11x=11 (divide both sides by the coefficient of x)
x=1
since x=1 , substitute x=1 into eqn 1 to get y
y-3x=0
y-3(1)=0
y-3=0
y=3
Using elimination method
y-3x=0....eqn (1)
2y+5x=11....eqn (2)
multiply eqn 1 through by 2 and eqn 2 through by 1 to eliminate y
2y-6x=0.... eqn 3
2y+5x=11.... eqn 4
subtract eqn 4 from from eqn 3
-11x=-11 (divide both sides by the coefficient of x)
x=1
substitute x=1 into eqn 2 to get y
2y+5x=11
2y+ 5(1) =11
2y+5=11
2y=11-5
2y= 6 (divide both sides by the coefficient of y)

The height of a candle decreases from 10 centimeters to 6 3/4 centimeters after burning for 1/2 hour
The true statement is as follows:
The product 13 / 4 × 2 can be used to find the unit rate in cm per hour.
After one hour, the height of the candle will have decreased by 6 1 / 2 cm.
What is rate?Rate is the ratio between two related quantities in different units.
The height of the candle decreases from 10 cm to 6 3 / 4 cm after burning for 1 / 2 hours.
6 3 / 4 cm = 27 / 4 cm
10 - 27 / 4 = 40 - 27 / 4 = 13 / 4 cm
Therefore, 13 / 4 cm of candles were lost in 1 / 2 hours.
Rate = 13 / 4 × 2 = 26 / 4 = 13 / 2 cm per hour
Therefore, the product 13 / 4 × 2 can be used to find the unit rate in cm per hour.
13 / 4 + 13 / 4 = 13 + 13/ 4 = 26 / 4 = 13 / 2 = 6 1 / 2 cm.
Therefore, after one hour, the height of the candle will have decreased by 6 1 / 2 cm.

divide Rs 120 between two students so that one gets 4 times as much as the other
Answer:
One gets Rs 24 and the other Rs 96.
Step-by-step explanation:
Number of parts = 1 + 4 = 5
So one student gets 1/5 of 120 and the other gets 4/5 of 120
120 * 1/5 = 24
120 *4/5 = 4*24 = 96.
Answer:
One would get 96 and another would get 24
Step-by-step explanation:
So first lets create an equation from the words where 4x is what one students has and x is what another has :
120 = 4x + x
Lets solve this now!
120 = 5x (divide by 5 on both sides)
24 = x (1st Student)
(Multiply by 4 on both side to get the second student)
96 =4x (2nd Student)

suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow parmbles. you are going to pull out one marble, record its color, remove it from the box and draw another marble. what is the probability of pulling out a red marble followed by a blue marble? the multiplication rule says to use P(red) P(blue).
1. Describe the probability of finding a red marble.
2. describe the probability of finding a blue marble.
3. describe the process of finding the probability of finding a red marble followed by a blue marble if the first marble was permanently removed?
4. what effect did removing the first marble from the box have on the problem
5. describe the probability of finding a red marble followed by the blue marble if the first marble is removed?
Answer:
Step-by-step explanation:
Part A
The probability of finding a red marble. P(red) = red / total
Total = red + yellow + blue
Total = 2 + 4 + 3
Total = 9
P(red) = 2/9 = 0.22222
Part B
P(blue) = blue / total
P(blue) = 3/8 = 0.375
This means that the red marble is permanently gone. The total is different. It is eight not nine.
Part C
The probability of red followed by blue is just the answers to A and B multiplied.
P(red) followed by blue = 2/9 * 3/8
P(red) followed by blue = 0.22222 * 3.75
P(red) followed by blue = 0.0833333
If you are confident of your concellation abilities you could do this as
P(red followed by blue) = 2/9 * 3/8 = 1/3 *1/4 = 1/12 = 0.083333....
Part D
Removing the first marble had the affect of reducing the total number of marbles to 8 and the number of reds from 2 downto 1
Part E

It is always helpful to rewrite a quadratic equation in standard form as a first step in solving it.
A. FALSE
B. TRUE
Answer:
A
Step-by-step explanation:
Now when I think of solving it, I think of finding the zeros. Now if you start with the form, for example:
[tex](x+3)(x-3)[/tex]
Then you can easily see the zeros are -3 and 3.
But if you start with the standard form:
[tex]ax^2+bx+c=0\\or\\x^2-9[/tex]
It will be harder to find the zeros and you would do the eqation or factor it.
So if your in the factored form don't go to standard to find the zeros.
The given statement is False.
What is a quadratic equation?An equation with highest degree two, is considered as a quadratic equation.
In standard form, the right side of an equation should be 0 and every component on the left side should be 1.
For example, x² = 4; to express this in standard form, move the number 4 to the left side of the equation, resulting in x² - 4 = 0.
If you are asked to find x in this circumstance, there is no need to write the equation in standard form; simply take this same real number of both of the equation's sides to find x.
Hence, it is not always necessary to write the quadratic equation in standard form then solve.

A pair of equations is shown below: y = 3x - 5 y = 6x - 8
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
See below
Step-by-step explanation:
y = 3x -5 <===== multiply this equation by -2 to get
-2y = -6x+10 now add it to the other equation(this will ELIMINATE x)
y = 6x-8
-y = +2
y = -2 then sub this in to oneof the quations to find x = 1
the two points will intersect at x,y = 1,-2 (because this satisfies both of the equations)
PART A
We start with: y = 3x - 5 y = 6x - 8
Elimination:
If we have two equations that = y, then we can make them equal each other:y = y3x - 5 = 6x - 8We then collect the x term together:3x - 6x = -8 + 5-3x = -3We can divide both sides by -3:x = 1Substitution
We can make one equation turn from a y= to an x=I decided to go with y = 3x - 5 (but it doesn't matter)We basically want to get it into x=y = 3x - 5y + 5 = 3x3x = y + 5 (I'm just flipping the equation to get x on the left for easiness)We then divide both sides by 3:x = [tex]\frac{y + 5}{3}[/tex]Don't forget we've also got y = 6x - 8So we just put x in!y = 6 × [tex]\frac{y + 5}{3}[/tex] - 8y = [tex]\frac{6}{3}[/tex] × (y + 5) - 8y = 2 × (y + 5) - 8y = 2y + 10 - 8y = 2y + 2Rearrange to get y on one side:-y = 2Times both sides by -1:y = -2We can now go back to...x = [tex]\frac{y + 5}{3}[/tex]By putting y = -2 in:x = [tex]\frac{-2 + 5}{3}[/tex]x = [tex]\frac{3}{3}[/tex] = 1PART B
We can find where they intersect/overlap by using elimination/substiutionWe've already covered both, and we get x = 1This means we've already go the x-coordinate of our point where the lines meet(x, y) = (1, ?)We just put our value of x into either equation (since x = 1 is where they meet)I'll go with y = 6x - 8y = 6 × 1 - 8y = 6 - 8 = -2We end up with (1, -2)!!!P.S.:
I've attached a screenshot of the graphs, notice how they meet at (1, -2)
