Worth 20 points hurry !
tickets to a concert were $2.50 for adults and $1 for students. $1200 was collected and 750 tickets were sold. write a system of linear equations that can be used to find how many adults (a) and how many students (b) attended.
how many students attended?

450 students and 300 adults

Step-by-step explanation:

how many adults (a) and how many students (s) attended.

Quantity:: a + s = 750 tickets

Value 2.5a+s = 1200 dollars

Subtract and solve for "a":

1.5a = 450

---

a = 300 (# of adults attending)

s = 750-300 = 450 (# of students attending)

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
