1) 25cm2 = 150cm2 (not sure, sorry)
2) 3 • x = 1.8
x = 0.6
(I replaced the gap with the letter x)
3) 1 + 2 + 3 + 4 = 3 + 7 = 10
4) -5 + - 7 + 10 + 10 = -12 + 20 = 8
5) -3 (4 + a) = -12 - 3a

the theatre charges $9 for each adult ticket and $6 for each child ticket. the theatre sold 144 tickets for the first showing of

Anna007 [38]

X=number of adult tickets
y=number of child tickets
I suggest this system of equations:
x+y=144
9x+6y=1164
we can solve this system of equations by substitution method.
x=144-y

9(144-y)+6y=1164
1296-9y+6y=1164
-3y=1164-1296
-3y=-132
y=-132/-3=44

x=144-y
x=144-44=100

Answer: the theatre sold 100 adult tickets and 44 child tickets.
