The cost e of materials for a deck varies jointly with the width w and the length 2. in c=$470.40 w hen w=12 and 1 -16, find the cost when w=10 and 1= 25.

the answer would be c:   ax + b = ax + c

step-by-step explanation:

150.6

all i did was i multiplied 5.02 by 30

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.
