Answer:

x = 2

Step-by-step explanation:

This triangle isosceles because of it's two marked congruent sides.

Using base angle theorem, reflexive property (the line in the middle is congruent to itself), and given, we can prove that the two triangles are congruent.

Now that we have proved triangle congruency (SAS), we know that:

17x-3 = 9x+13

Plus 3 on both sides and minus 9x on both sides

8x = 16

Divide by 8 on both sides to isolate x

x = 2

Hope this helps :)

Have a nice day!

for the opening day of a carnival, 800 admission tickets were sold. The receipts totaled $3775. Tickets for children cost $3 eac
zloy xaker [14]
Total tickets sold  = 800
Total revenue = $3775

Ticket costs:
$3  per child,
$8  per adult,
$5 per senior citizen.

Of those who bought tickets, let
x =  number of children 
y = number of adults
z = senior citizens

Therefore
x + y + z = 800                   (1)
3x + 8y + 5z = 3775           (2)

Twice as many children's tickets were sold as adults. Therefore
x = 2y                                (3)

Substitute (3) into (1) and (2).
2y + y + z = 800, or
3y + z = 800, or
z = 800 - 3y                        (4)
3(2y) + 8y + 5z = 3775, or
14y + 5z = 3775                 (5)

Substtute (4) nto (5).
14y + 5(800 - 3y) = 3775
-y = -225
y = 225
From (4), obtain
z = 800 - 3y = 125
From (3), obtain
x = 2y = 450

Answer:
The number of tickets sold was:
450 children,
225  adults,
125 senior citizens.
