Answer:
431 reserved tickets, 1356 general tickets
Step-by-step explanation:
4x + 3y = 5792
x + y = 1787
Start with these equations and guess numbers and eventually you'll be right
1000x + 787y =6361 WRONG
700x + 1087y = 6061 WRONG
500 x + 1287y = 5861, close but WRONG
430 x + 1357 y = 5791, very close but WRONG
431 x + 1356y = $5792, CORRECT
431 + 1356 = 1787 tickets sold
Answer:
x = 3.75
Step-by-step explanation:
So, lets start with what we know.
Line = 180 degrees
Triangle = 180 degrees, a + b + c = 180
So, we can form the equations,
17x - 1 + <CDB = 180
-17x + 1 -17x + 1
<CDB = 181 - 17x
and
84 +7x + 5 + <CDB = 180
89 + 7x + <CDB = 180
-89 -89 + 7x
<CDB = 91 + 7x
Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other
181 - 17x = 91 + 7x
-91 +17x -91 +17x
90 = 24x
90 / 24 = 24x / 24
3.75 = x
x = 3.75
There, you have it, x is 3.75
