What is the value of x? [2(+10)] (3x-30)

x = 10

Step-by-step explanation:

[2(+10)] (3x-30)

Solve :

[2(+10)] (3x-30)

[20] (3x-30) = 0

60x - 600 = 0

60x = 600

x = 600/60

x = 10

Step-by-step explanation:

Given:

For the given equation, equating to zero for standard form equation to find 'x'

On solving the equation the value of x is 10

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

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.
