Question:
The local community theater sold a total of 240 tickets for Saturday night’s performance. They sold 180 more full-price tickets than discount tickets. Which system of equations can be used to model this situation?
Answer:


Step-by-step explanation:
Given

Represent the number of full price with x and discounted price with y.
From the question:
x = 180 more than y
So:

Also, a total of 240 were sold.
So:

Hence, the equations are:


Solving further;
Substitute 180 + y for x in 


Solve for 2y


Divide through by 2

Recall that: 


Hence:
<em>Full Price = 210</em>
<em>Discounted = 30</em>

Answer:
1) x = -1 or x = -10 (either of them are both correct)
2) x = 3 or x = -5
Step-by-step explanation:
Let's solve your equation step-by-step.
x2 + 11x + 10 =0
Step 1: Factor left side of equation.
(x + 1)(x + 10) = 0
Step 2: Set factors equal to 0.
x + 1 = 0 or x +10 = 0
x = −1 or x = −10
Answer:
x = −1 or x = −10
2x^2 + 4x − 30 = 0
Answer:
x = 3 or x = −5
In the first step when the student did -2x-3 they didn’t make the sign positive. It should be 4=-2+6, not 4=-2-6
