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

Well gradient means "slope" I just found out from searching the web.
First let's put y = 4 + 2x into slope intercept form of y = mx + b
y = 2x + 4
"m" is the slope, in this equation it would be 2.
The slope or "gradient" is 2.
The y-intercept of any equation in slope intercept form is the value of "b"
In this equation, the y-intercept is 4.
2 1/8-1 19/40
Make the mixed numbers into improper fractions
17/8 - 59/40
Make the fractions have the same common denominator
85/40 - 59/40
Subtract the numerators while keeping the denominators the same
Final Answer: 26/40 or 13/20
