Answer:

x + 1

Step-by-step explanation:

3x -(2x +4)+5

Open bracket first by multiplying bracket by -

3x - (2x + 4) + 5

3x (- × 2x) -(+4) + 5

= 3x - 2x - 4 + 5

= x - 4 + 5

= x + 5 - 4

At Friday's football game, 1,294 tickets were sold for a total amount of $8,816.00. If each student ticket costs $5.00, and each

NeTakaya

Answer:

512 student tickets.

Step-by-step explanation:

Let x be number of student tickets and y be number of adult tickets.

We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:

$x+y=1294...(1)$

We are also told that each student ticket costs $5.00, and each adult ticket costs $8.00 and 1,294 tickets were sold for a total amount of $8,816. We can represent this information as:

$5x+8y=8,816...(2)$

From equation (1) we will get,

$y=1294-x$

Substituting this value in equation (2) we will get,

$5x+8(1294-x)=8,816$

$5x+10352-8x=8,816$

$-3x+10352=8,816$

$-3x=8,816-10352$

$-3x=-1536$

$x=\frac{-1536}{-3}$

$x=512$

Therefore, 512 student tickets were purchased at Fridays football game.

Step-by-step explanation:

By adding the like terms you get

-12x + 10 = -10x + 8

then you add 12x to both sides and subtract 8 to both sides and get

2 = 2x

yulyashka [42]

Answer:

4164.69504π

Step-by-step explanation:

So the volume of a cone is πr^2 * h / 3

r = 15.072 / π

h = 55

15.072 / π squared * π = 227.165184π

227.165184π * 55 / 3 = 4164.69504π
