UV=13
UW=2y-9
WV=y-5
UV=UW+WV
UV=(2y-9)+(y-5)=2y-9+y-5=3y-14
13=3y-14
27=3y
y=27/3=9
Solution is A, y=9
Why Farmland is Abandoned:
As groundwater pumping increased, water tables dropped, requiring pumping from deeper levels and at greater costs. Because of the increased cost, irrigation became prohibitively expensive. Farms thus were abandoned as unprofitable, especially in Cochise and Pinal counties.
It has nothing to do with the Moon. It is the time of year when, over the northern hemisphere, the Sun is near or at its highest apparent position in the sky and the rays are most direct Earth's axial tilt points the Northern Hemisphere more towards the sun in June, causing the sun to ride higher in the sky. Summer for us, Winter South of the Equator.
