Answer:

6x-2y=26

+

-3*(2x+3y=5)=-6x-9y=-15

-11y=11 y=-1

So

6x-(2*(-1))=26

6x+2=26

6x=26-2=24

X=24:6=4

So x=4 and y=-1

2x+3y=5

2*4+3*(-1)=5

8-3=5 see

iragen [17]

Answer:

The answer is 2.5135145

Step-by-step explanation:

  • The irrational number between 5,25 and 5,26
  • 2.5135145...
  • The number is non-terminating and non-recurring. Hence, it is an irrational number.
  • A real number that cannot be expressed as a simple fraction is called an irrational number.
  • It is impossible to express in terms of a ratio.
  • If N is irrational, it is not equal to p/q, where p and q are integers and q is not equal to 0.

Here are three stories:
aev [14]

Answer:

1)

a) 6x+3 = 27

b) x=4

c) We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.

2)

a) 3x + 6 = 27

b) x= 7

c) We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.

3)

a) 27x + 3 = 6

b) x= 1/9

c) We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture

Step-by-step explanation:

1. A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the  show.

a)  Decide which equation represents each story. What does x represent in each equation?

Let x be price of one ticket.

The equation will be: 6x+3 = 27

b. Find the solution to each equation. Explain or show your reasoning,

Now solving the equation:

6x+3=27

6x=27-3

6x=24

x=24/6

x=4

So, we get x = 4

c. What does each solution tell you about its situation?

We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.

2. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6  ounces left for himself.

a)  Decide which equation represents each story. What does x represent in each equation?

Let x be amount of juice poured.

The equation will be: 3x+6 = 27

b. Find the solution to each equation. Explain or show your reasoning,

Now solving the equation:

3x+6=27

3x=27-6

3x=21

x=21/3

x=7

So, we get x = 7

c. What does each solution tell you about its situation?

We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.

3. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6  ounces left for himself.

a)  Jada works for 6 hours preparing for the art fair. She spends 3 hours on a sculpture and  then paints 27 picture frames.

Let x be time spend on each picture frame.

The equation will be: 27x+3=6

b. Find the solution to each equation. Explain or show your reasoning,

Now solving the equation:

27x+3=6

27x=6-3

27x=3

x=3/27

x=1/9

So, we get x = 1/9

c. What does each solution tell you about its situation?

We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture
