Lindsey needs a jeweler to repair her earings. jeweler a is offering her services for an initial $125 in addition to $15 per hour. jeweler b is offering his services for an initial $140 in addition to $12 per hour. when will the two jewelers charge the same amount of money

Explanation:

Jeweler A: y=15x+125       (y=15(1)+125)

Jeweler B: y=12x+140        (y=12(1)+140)

        Graph:

A                 - x -               B

140                1                  152

155                2                 164

170                3                 176

185                4                 188

200               5                 200

The two jewelers meet at the 5th hour.

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.
