Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)
Alternate interior angles are congruent. Therefore, set the two angles equal to each other and solve for x.
3x+4= 115
3x+4 -4 = 115 -4
3x = 111
x= 111/3---> 37. Therefore, x = 37.
Answer:
y = m x + b equation of a straight line
m = (y2 - y1) / (x2 - x1) slope of line
m = (17 - 10) / (-36 - 48) = 7 / -84 = -1 / 12
y = -x / 12 + b equation of line
Or b = y + x / 12
If y = 10 and x = 48 then b = 10 + 48 / 4 = 14
if y = 17 and x = -36 then b = 17 - 36 / 12 = 14
So b = 14 and y = -x / 12 + 14
