A=number of adult tickets
s=number of student tickets
so
total of 89 tickets sold
a+s=89
total collected was 1119
15a+11s=1119
so we have
a+s=89
15a+11s=1119
subsitution
a+s=89
minus s from both sides
a=89-s
subsitte 89-s for a in the other equation
15a-11s=1119
15(89-s)+11s=1119
1335-15s+11s=1119
1335-4s=1119
minus 1335 from both sides
-4s=-216
divide both sides by -4
s=54
subsitute back
a=89-s
a=89-54
a=35
35 adult tickets
54 student tickets

Answer:
Below
Step-by-step explanation:
You can use the quadratic formula:
x = [-10 ± √(10^2 - 4*-1* -8)] / -2
You can write it 3 different ways. The first way is fraction form,24/36. The next way is actually writing the ratio completely, for example,$24 to $36. Or the "to" method. Get it? There's a "to" in the middle of the numbers. The last way is writing the ratio down with this : thing. For example 24:36. If you have further questions, please leave it in the comments.
Answer:
22 games
Step-by-step explanation:
From the barchart :
We can obtain the total number of goals scored :
Home goals (quarter 1 to quarter 4) :
= (9 + 6 + 8 + 7) = 30
Away goals (quarter 1 to quarter 4) :
= (2 + 7 + 4 + 5) = 18
Using the relation :
Mean goals scored = total goals scored / number of games played
Home games :
Mean goals = 2.5
Number of home games played = total goals / mean goals scored
= 30 / 2.5
= 22
Away games :
Mean goals = 1.8
Number of away games played = 18 / 1.8
= 10
Number of home and away games played in total = 22 + 10 = 32 games
