Part b is 64 i think
hope this helps:))
The total degrees of a triangle is 180.
So
37+63=100
And well
180-100=80
U=80

Answer:
350 adult tickets were sold
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then the number of student tickets is (a+69) and the total number of tickets sold is ...
a + (a+69) = 769
2a = 700 . . . . . . . . subtract 69
a = 350 . . . . . . . . . divide by 2
350 adult tickets were sold.
Answer:
The coordinates are x = -1 and y = -2.
Step-by-step explanation:
Given:
Equations are 2x-4y=6 and 3x+y=-5.
Now, to find the coordinates.
...........(1)
...........(2)
So, first we solve the equation 1 to get the value of
.

Subtracting both sides by
we get:

Dividing both sides by 2 we get:

Now, we put the value of
in equation 2 to get
.




On solving the whole equation we get :

And, now putting the value of
in equation (1) we get
:





on solving we get:

Therefore, the coordinates are x=-1 and y=-2.
