Suzi starts her hike at 270 feet below sea level. When she reaches the end of the hike, she is still below sea
level at -133 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the
hike?

thats not a system of equations, that is a solution

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20

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.

wouldn't that be a) 1

4=4x then divide 4 on both sides and you get x=1
