An electrician has 120 to spend on interior light fixtures. the wholesale price for 13 watt low energy lamp is 4 $ the price for high energy lamps is 5$ . how does the total price of the low energy lamps compare to the high energy lamps, and how does the price of the high energy lamps compare to the low energy lamps

12cm

the answer is d

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
