Answer:
Submarine W. the closest submarine is the one with the lowest depth, -1.5 km (which should actually be written as an absolute value, 1.5km, depth can't be negative).
3x-5=19-x
3x-5-19+x=0
4x-24=0
4x=24
x=6
True.
two angles would be complementary if the sum of their angle measures is 90 degrees.
60 degrees and 30 degrees make a complementary angle while 90 and 90 degrees make a supplementary angle.
X = -2 and y = -6. your welcome :)
