Solve the following system of equations.

2x+y=3

x=2y+1

Make sure there are NO SPACES in your answer. Include a comma in your answer.


ANSWER: {( )}

Answers

Answer 1
2x+y-3=0,x-2y=1 okay that's the answer good luck
Answer 2
subtract y from both sides
now we have
2x = -y + 3
divide both sides by 3
x= -y/2 + 3/2
the other x equals 2y +1, set these equal to eachother

2y + 1 = -y/2 + 3/2

add y/2 to both sides

2.5y + 1 = 3/2

subtract 1 from both sides

2.5y = 0.5

divide both sides by 2.5

y=0.2

plug in 0.2 for y in an original equation

x = 2(0.2) + 1

solve

x = 1.4

ANSWER:
x= 1.4
y= 0.2

Pentagon PQRST is drawn on a coordinate plane below. what rule best represents a dilation to create pentagon PQRST with a scale factor of 1/2 and with the origin as the center of dilation?

Answers

Answer: [tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Step-by-step explanation:

Dilation is a transformation, in which the size of the image gets changed but not shape.

The rule of dilation with scale factor k and wither origin as center of dilation :

(x,y) → (kx, ky)

Here , [tex]k= \dfrac12[/tex] , center of dilation = Origin

Then, the rule best represents a dilation to create pentagon PQRST will be :

[tex](x,y) \to (\dfrac12 x, \dfrac12 y)[/tex]

Mike and Andy are each reading the same book. Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday. Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday. Andy says that altogether he read more of the book on Tuesday and Wednesday than Mike. Is Andy correct?


Select from the drop-down list to complete the sentence. Explain your answer by typing in the box.


is andy correct or incorrect




Explanation:
ASAP

Answers

Andy is wrong, on tuesday they read the same amount, but on wednesday mike read more than andy because 1/3>1/5 so mike read more altogether, hope this helps :) plz give branliest if it does

In the second attempt, Mike read (1/3)rd of the book which is more than

(1/5)th of the book Andy read.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given,  Mike read 2/4 of the book on Tuesday and 1/3 of the book on Wednesday.

Therefore in total, Mike read (2/4 + 1/3) of the book.

= (6 + 4)/12.

= 10/12.

= 5/6 of the book.

Also given, Andy read 1/2 of the book on Tuesday and 1/5 of the book on Wednesday.

Therefore in total, Andy read (1/2 + 1/5) of the book.

= (5 + 2)/10.

= 7/10.

As the fractions (2/4) which Mike read and (1/2) Andy read they have read the same amount of the book but in the next time Mike read 1/3 of the book and 1/5 and we know 1/3 is greater than 1/5.

So, Mike read more of the book than Andy.

Answer: 0.11

This question is simple. Do not worry. I will get it done for you. What we need to do here is to divide 2/3 by 6 because you have 2/3 of the salad leftover and you want to split it among 6 friends. 6/1 is the same as 6 because if you divide 6 and 1, you get 6. Hence, 2/3 / 6/1. However, we need to flip the second fraction. So, 6 is the denominator and 1 is the numerator. When we do that, the question is now a multiplication question.

2/3 x 1/6 = 2/18

However, the fraction can be simplified by dividing both sides by 2.

2/2 x 18/2 = 1/9

Hence, each friend receives 1/9 of the salad.
