4. The band at Jason's high school had a concert for charity. They raised $15000. Adult tickets were $5 each and student tickets

grin007 [14]

Answer:

A. x + y = 4000

5x + 3y = 15000

Step-by-step explanation:

Total amount raised = $15000

cost of adult tickets = $5

cost of student tickets = $3

Total number of tickets sold = 4000

number of adult tickets sold = x

number of student tickets sold = y

Then we can say,

total number of ticket sold = number of adult tickets + number of student tickets

4000 = x + y

⇒ x + y = 4000 ............. 1

Also,

5x + 3y - 15000 ............. 2

the equations required are:

x + y = 4000

5x + 3y - 15000

2x - y = 3 and x+ y = 0

Kamila [148]

Answer:

<u><em>I think this is it.....If not let me know</em></u>

2x - y = 3

Slope = 2

x - intercept = 3/2 = 1.50000

y - intercept = 3/-1 = -3.0000

x + y = 0

Slope = -2.000/2.000 = -1.000

x - intercept = 0/1 = 0.0000

y - intercept = 0/1 = 0.0000

Solve this linear system. 2.4 = 0.3 x + 0.4y 5x = 2 + 6y

hammer [34]

$\left \{ {{2.4 = .3x + .4y} \atop {5x = 2 + 6y}} \right.$

5x = 2 + 6y
Divide both sides by 5
x = 6/5y + 2/5

Input in the other equation.

2.4 = .3(6/5y + 2/5) + .4y
2.4 = .36y + .12 + .4y
2.4 = .76y + .12
Subtract .12 from both sides.
2.28 = .76y
Divide both sides by .76
3 = y

x = 6/5(3) + 2/5
x = 18/5 + 2/5
x = 20/5 = 4

How do you solve: 2(b - 5) + 7b-4

Alinara [238K]

2(b-5)+7b-4
Solve 2(b-5) to get 2b-10
Combine your like terms 2b-10+7b-4
Solve 2b+7b to get 9b
Solve -10+(-4) to get -14
So your answer is
9b-14
