If A is 24 and B is 4 and C is 84 , Please solve this 2 x A + C - 67 x B - 100 + C =

For Brainliest

-152

Step-by-step explanation:

You need to subsitute the numbers given for the variables, be sure to use parenthesis as to not get confused

a=24 b=4 c=84

1.) 2 x (24) + (84) - 67 x (4) - 100 + 84 =

2.a) PEMDAS (aka Order of Operations)

2.b) 48 + 84 - 268 -100 + 84 =

3.) Combine like terms to make easier : (48+84+84) + (-268-100)

4.) = 216 + (-368) = -152

-152

Step-by-step explanation:

2*24+84-67*4-100+84 =

48+84-268-100+84 =

132-368+84 =

-236+84 =

= -152

Hope this helps.

answer:      

step-by-step explanation:

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.
