Answer:

4698

Step-by-step explanation:

We know that 1 person is on 3quares, so we need to know how many squares value 3 has every room. We do that in the way- we calculate surface area of every room and divide with 3.

First room has surfaxe 75x75=5625

5625/3=1875

So the first room can have 1875 persons.

2nd room has surface 130x60=7800

7800/3=2600

The 2nd room can have 2600 persons.

3th room has 180 sets, so it is for 180 persons.

We also know that tey can add on every exit 10 more, and they have 4 exits, so it is

10x4=40

The total tickets they can sell is:

1875+2600+180+40=4695

Solve for x: 2x – y = (3/4)x + 6.
Artyom0805 [142]

Answer:

B

Step-by-step explanation:

2x – y = (3/4)x + 6.

or, 2x - (3/4)x = y + 6.

or, (8x -3x)/4 = y + 6.

or, 5x/4 = y + 6.

or, 5x = 4(y + 6).

or, 5x = 4y + 24.

or, x = (4y + 24)/5.

Therefore, x = 4(y + 6)/5.

an equation for a line in the plane allows you to find x- and y-coordinates of any point on that line true or false?
BARSIC [14]

Answer:

True

Step-by-step explanation:

When you are given an equation of a line in the plane, it´s like if they´ve given you the map to a line, and in this case it´s really easy to calculate the value of the different points on X and Y and by that you just have to immagine a value for one of the variables to calculate the other one, most cases is always X the one that you give the value to, and then you just calculate the Y.
