Find the solution to the system of equations
Neko [114]

Answer:

x=1

y=-4

Step-by-step explanation:

Since -x-3=y subsitue that in at the top equation

- x - 3 =  - 7x + 3

- x =  - 7x + 6

6x = 6

x = 1

Plug x=1 back into the equation to solve for y.

y =  - 7(1) + 3

y =  - 4

Are total emissions or per-capita emissions a better gauge when comparing the co2 emissions of various countries? why? emissions
algol13

The emissions per capita measurement is a better because it shows the number of people divided by the emissions.

<h3>What is the difference between total emissions and emissions per capita?</h3>

The emissions per capita show the emissions per each citizen or inhabitant, while the total emissions show only the emissions of the country.

<h3>Which one is better?</h3>

The per capita gauge is better because whether a country is polluting more or not depends on how much each citizen pollutes. This information is useful to create laws that reduce pollution.

14. The maximum capacity for seating in a theater is 500 people. The theater sells two types of
Eva8 [605]

Taking into account the definition of a system of linear equations, the amount of adult tickets sold is 356 and the amount of child tickets sold is 144.

<h3>System of linear equations</h3>

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values ​​of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.

<h3>Amount of ticket sold</h3>

In this case, a system of linear equations must be proposed taking into account that:

  • "x" is the amount of adult tickets sold.
  • "y" is the amount of child tickets sold.

The maximum capacity for seating in a theater is 500 people. If they sold out on a certain showtime, this is represented by x+y=500.

On the other side, the theater sells two types of tickets, adult tickets for $7.25 each and child tickets for $4 each and the made a total of $3,157. This is represented by 7.25x +4y=3157.

So, the system of equations to be solved is

\left \{ {{x+y=500} \atop {7.25x+4y=3157}} \right.

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, isolating the variable x from the first equation you get:

x=500 - y

Substituting this expression in the second equation you get:

7.25× (500 -y) +4y=3157

7.25×500 - 7.25y +4y=3157

3625 - 7.25y +4y=3157

- 7.25y +4y=3157 -3625

-3.25y= -468

y= (-468)÷ (-3.25)

<u><em>y= 144</em></u>

Substituting this value in the expression x=500 - y you get:

x=500 - 144

<u><em>x=356</em></u>

Remembering that "x" is the amount of adult tickets sold and "y" is the amount of child tickets sold, you get that the amount of adult tickets sold is 356 and the amount of child tickets sold is 144.
