1. 0 - 34 + 13 - 5 = -26.....26 ft below the surface
2. y = 15x + 50
220 = 15x + 50
220 - 50 = 15x
170 = 15x
170/15 = x
11 1/3 = x......he worked 11 1/3 hrs.......not sure about this...because it does not specify how many visits he made...but if this was just for 1 visit, then he worked 11 1/3 hrs

Answer:
your picture has 2 main points
Step-by-step explanation:
Answer:
y=50
x=30
z=100
Step-by-step explanation:
x+20=y
2y=z
x+y+z=180
x+y+2y=180
3y+x=180
-y+x=-20
4y=200
y=50
x=30
z=100
