Answer:
5x-18=4x+7 ( vertical opposite angle)
5x-4x=7+18
x=25
1: convection
2: insulator
3: no heat (because all are same temp...pretty sure)
4: weight and electric potential energy
5: kinetic to potential
6: (I think) nuclear to kinetic to chemical
7: increase tread
8: temp is a factor of thermal energy
Answer:
A mathematical proof is an inferential argument for a mathematical statement, showing that the stated assumptions logically guarantee the conclusion.The argument may use other previously established statements, such as theorems; but every proof can, in principle, be constructed using only certain basic or original assumptions known as axioms, along with the accepted rules of inference.
Its got to be in there.
The answer is x= -5 ...explained... -2x + 5 -35x= 190...-37x +5 = 190 ... now subtract 190-5 = 185... divide 185 by - 37 and get -5
