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>

Find the values for x and y
USPshnik [31]

Answer:

x = 55

y = 70

Step-by-step explanation:

Since all three sides are equal, as indicated by the lines on the sides, all three angles are equal

Since a triangle is equal to 180 degrees

180/3 = 60

Each angle is 60 degrees

x+5 = 60

Subtract 5 from each side

x +5-5 = 60-5

x = 55

y-10= 60

y-10+10 = 60+10

y= 70

Please help with this area question. I have gotten my answer but I am not too sure about it, and want to make sure my reasoning
Pie

Answer:

D

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Since the length of the base and the height of the triangle is equivalent to the length of a side of the square, s,

area of triangle

= ½ ×s ×s

= ½s²

Given that the area of the triangle is 12.5 units²,

½s²= 12.5

Multiply both sides by 2:

s²= 12.5(2)

s²= 25

Square root both sides:

s =  \sqrt{25}

s= 5 units

(reject negative value since s > 0)
