20*2=40
40*50=2000
2000/60=33.33
about 33 hours by lifting by hand
The 3rd one I thinkkkkk ??
Answer:
y=-2x+2
Step-by-step explanation:
The slope is -2x, meaning that the y-intercept can be found by working backwards from the given point. If the y value of the point is 4, subtracting 2 to get you to the point (0, 2) would provide the y-intercept.
Slope Intercept form is y=mx+b (m is the slope, x is the entered value, b is the y intercept)
All you need to do is multiply
11 x 12 x 9
=1188
