Answer:
Where's exercise 11
Step-by-step explanation:
Answer:
let the number of door tickets be x
so, eventually the number of advanced tickets will be. x-30
the total cost=2630.
(x-30)3+5x=2630
3x-90+5x=2630
8x-90=2630
8x=2630+90
8x/8=2720/8
x=340
x-30
340-30
310.
total tickets sold=310+340=650
Therefore, the total tickets bought was 650, 310 was advanced and 340 was door tickets
The equation of the line is
y = 5x-11
N-10=32
add 10 to both sides
n-10+10=32+10
-10+10=0
n=42
