Step-by-step explanation:
There are 24 hours in one day. when you count from 1-24, (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24) the number 7 shows up twice
A=adult tickets
c=chlderenticekts
s=sinior tickets
a=c
a+c+s=120
2a+s=120
total made is 1100
12a+6c+10s=1100
sub
a=c
12a+6a+10s=1100
add
18a+10s=1100
multiply first equation by -9 and add to other equation
-18a-9s=-1080
18a+10s=1100 +
0a+s=20
s=20
20 senior tickets were sold
answer is B
Answer:1
Step-by-step explanation:
Answer:
First equate 3x + 7 to any unknown
3x + 7 = P
Then make x the subject of the formula
3x + 7 = P
3x + 7-7= P-7
3x = P-7
3x ÷ 3 = (P-7) ÷ 3
x = (P-7) ÷3
Then interchange x with the unknown which I have as P
x = (P-7) ÷ 3
P = (x-7) ÷ 3
Then inverse of f(x)
is;
f-1(x) = (x-7) ÷ 3
