Answer:

62 degrees

Step-by-step explanation:

First, it is important to note that all three angles in a triangle add up to be 180 degrees, and if you draw a straight line extending off the side of a triangle, the outside angle and the inside angle are supplementary (they add to be 180 degrees). So,(3x+3)+(2x+4)-180=measure angle F, and 180-(7x-5)=measure angle F according to the rules respectively. Since both of these equations are equal (they both equal the measure of angle F) we can set them equal to each other to find the value of x=> 180-(7x-5)=(3x+3)+(2x+4)-180=> 180-7x-5=3x+3+2x+4-180. Now combine like terms=>175-7x=5x-173. Now, add 7x to both sides and add 173 to both sides to get the variables on one side of the equation=> 175+173-7x+7x=5x+7x-173+173 (the 7x and -7x on the left side and the 173 and -173 on the right side cancel out) =>348=12x. Divide both sides by twelve to find x=> 29=x. Now, plug 29 into what is given for angle FDE=> 2(29)+4=

58+4=

62 degrees

20 POINTS PLEASE HELP
Temka [501]
1. It's in point-slope form right now
y - 7 = -x - 4
x + y = 3

2. Find the slope through (y2-y1) / (x2-x1)
The slope is 3.
Use the point slope formula: y - 9 = 3 (x - 8)
y - 9 = 3x - 24
y = 3x - 15

3. a. standard form
b. point-slope
c. slope-intercept
d. standard

5. Use point-slope: y - 8 = 6 (x - 3)
y - 8 = 6x - 18
-6x + y = -10

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>
