#9A)15>7-t\3( multiply both sides by 3
45>7-t(collect the like terms
45-7=-t
38>-t
answer=-38<t
#8)-15>_7+2m
-15-7>_2m
-22>_2m (divide both sides by 2
-11>_m
#7)1-4n>_37
-4n>_37-1
-4n>_36(divide both sides by -4
n<_-9
#6)23>_3x-4

27>_3x
9>_X
#5)-6>w\-4(multiply both sides by -4)
24>w(choice D is the correct answer

True.

Step-by-step explanation:

You can see it with the cartesian plane. The cartesian plane are two intersecting perpendicular lines. The intersection point is the (0,0) and each cuadrant is 90°. 90°(4 cuadrants) = 360° .
