Answer:
36
Step-by-step explanation:
I started by making the expression with the same units on both sides:
1 in = 3(12 in)
I then simplified the equality to find the scale:
1 in = 36 in
Your goal is to get h by itself -18(2h+4)+12=-74
first distribute
-36h-72+12=-74
second combine like terms
-36h-60=-74
third get h by itself by adding 60 to the other side
-36h=-14
forth divide -36
h=0.38
to check your answer you plug in your answer to the equation and you'll get -73.68 but round it to nearest 10th you get -74
F (x) = 5(4) ^x Is the right answer
(a) 
= 4n + 8
(b) row 13 has 60 seats
(a)
the sequence of seats is an arithmetic sequence whose n th term is
= 
+ (n - 1 )d
where is the first term and d the common difference
here the sequence is 12, 16, ....
with = 12 and d = 16 - 12 = 4, thus
= 12 + 4( n - 1 ) = 12 + 4n - 4 = 4n + 8
(b)
calculate the number of rows n when 60 seats
solve 4n + 8 = 60 ( subtract 8 from both sides )
4n = 52 ( divide both sides by 4 )
n = 13 ← number of rows
