-45 is the answer to 2+9-56+
Answer:
15. y<1 16. y>or=-2 17. y>0 18. y<or=3 19. y<or=1200
Step-by-step explanation:
From the figure, its clear that the compass drew arcs like below:
With A as centre, and more than half of the length of AB as radius, one arc is drawn.
With the same radius, with B as centre, another arc is drawn.
The points of intersections of the arcs are X and Y.
Clearly, this is the construction of a perpendicular bisector of the line segment AB.
Hence, if we draw a line segment through XY, it will be a perpendicular bisector of AB.
If one box contains 10 grapefruits and there were 20,400 boxes in one season, then all we need to do is to multiply 20,400 by 10:
20,400 * 10 = 204,000
So the citrus grower shipped 204 thousand grapefruits.
