Solve the following system of equations. 2x+y=3 I= 2y - 1 x= y=

marin [14]

Note: I am assuming your second equation is:

x = 2y - 1

Answer:

The solution to the system of equations is:

x = 1

y = 1

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

$\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}$

Arrange equation variables for elimination

$\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}$

Multiply x-2y=-1 by2: 2x-4y=-2

$\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}$

subtracting the equations

$2x-4y=-2$

$-$

$\underline{2x+y=3}$

$-5y=-5$

now solve -5y = -5 for y

$-5y=-5$

Divide both sides by -5

$\frac{-5y}{-5}=\frac{-5}{-5}$

Simplify

$y=1$

For 2x+y=3 plug in y=1

$2x+1=3$

subtract 1 from both sides

$2x+1-1=3-1$

Simplify

$2x=2$

Divide both sides by 2

$\frac{2x}{2}=\frac{2}{2}$

Simplify

$x=1$

Therefore, the solution to the system of equations is:

x = 1

y = 1

So what would the correct answer be?

Varvara68 [4.7K]

No, Kira's reasoning is not correct, the correct answer is 3 1/2

Steps To Solve

1. subtract 61/4 - 2 3/4

2. Since you cannot subtract you add the denominator to the numerator

3. leave the denominator the same

4. once you do that decrease the whole number by one

5. your answer should be 3 1/2

Hope I Helped =)

Suppose a bag of marbles contains five green marbles, three blue marbles, six yellow marbles, and four white marbles. Maria shak

Nimfa-mama [501]

Answer:

a) blue = 1/6

b) white = 2/9

c) green or yellow = 11/18

d) neither blue nor yellow = 1/2

Step-by-step explanation:

First, you have to find the total marbles Maria has in the bag.

5 green + 3 blue + 6 yellow + 4 white = 18 marbles.

To find the probability you can use the formula:

probability = favorable outcomes / total number of possible outcomes

a) For blue

the amount of blue marbles are 3, so the probability is 3/18, simplifying the fraction you get 1/6.

b) For white

the amount of white marbles are 4, so the probability is 4/18, simplifying the fraction you get 2/9.

c) For green or yellow

the amount of green marbles are 5 and the amount of yellow marbles are 6, so the probability is 11/18.

d) neither blue nor yellow

the amount of blue marbles are 3 and the amount of yellow marbles are 6, so there are 9 out 18 that are not blue nor yellow, so the probability is 9/18, simplifying the fraction you get 1/2.

Brainliest, 35 points Just a little confusedo n this one

Verdich [7]

Answer:

Step-by-step explanation:

There are 10 cards total

P( not pink) = cards not pink/ total = 6 non pink cards /10 = 3/5

We replace the card so we still have 10 cards total with the same color distribution

P( yellow) = cards that are yellow /total = 1/10

Multiply the probabilities

P( not pink, yellow) = 3/5 * 1/10 = 3/50 = 6/100 = 6%
