He would have to sell at least 19 vacuums.
Let n represent the interger l, the three consective intergers are represented by



The second one represent

Simplify both sides






The intergers are 16,18,20
I think the answer is 50 because the smallest number that rounds to 30 is 25 and twice 25 is 50
The m in the equation is the slope and the y-intercept is the b.
y=1x-1
y=mx+b
When finding the -3√3 curved line, we look at the tangent of the angle. Since it has a negative beginning, we subtract the angle of the tangent, 30 degrees, from 180 degrees. Thus the angle
It has 90+60=150 degrees
