a local community theather 240 tickets for Saturday nights performance they sold 180 more st full price then the discount ticket

gizmo_the_mogwai [7]

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:

$x = 180 + y$

$x + y = 240$

Step-by-step explanation:

Given

$Tickets = 240$

Represent the number of full price with x and discounted price with y.

From the question:

x = 180 more than y

So:

$x = 180 + y$

Also, a total of 240 were sold.

So:

$x + y = 240$

Hence, the equations are:

$x = 180 + y$

$x + y = 240$

Solving further;

Substitute 180 + y for x in $x + y = 240$

$180 + y + y = 240$

$180 + 2y = 240$

Solve for 2y

$2y = 240 - 180$

$2y = 60$

Divide through by 2

$y = 30$

Recall that: $x = 180 + y$

$x = 180 + 30$

$x = 210$

Hence:

<em>Full Price = 210</em>

<em>Discounted = 30</em>

Factoring Quadratics - Please help; will mark Brainliest!

rosijanka [135]

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

Correct the error a student made when solving the equation 4=-2(x-3). What is the correct solution?

Murrr4er [49]

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
