I believe it should be quadrant 1
H: hours
45h + 45 = 30h + 75
15h + 45 = 75
15h = 30
h = 2 hours
45 ( 2 ) + 45 = 30 ( 2 ) + 75
90 + 45 = 60 + 75
135 = 135
Therefore the awnser is 2 hours.
Answer:
x = 71
Step-by-step explanation:
18(x + 1) = -54
to start off, subtract 18 from both sides
18 - 18(x + 1) = -54 - 18
that should give you
x + 1 = 72
(its safe to take out paranthesis from problem by now) now take away 1 from each side
x + (1 - 1) = 72 - 1
that should give you
x = 71
