I hope that
helps!
3x-8 = 8x+4
subtract 3x from each side
-8 = 5x+4
subtract 4 from each side
-12 = 5x
divide -12 by 5 to get x
x = -12/5 = -2.4
Answer:
Semiconductors are somewhere in-between conductors and insulators. This means that they are specific when it comes to conducting electricity meaning that their conduction of electricity varies based on their condition at the time.
For instance, they can conduct electricity when heated.
Properties:
1. Perfect insulator at Absolute Zero.
As mentioned above, semi conductors are better at conducting electricity when they are heated. At Absolute zero - the lowest temperature possible - therefore, these materials would conduct absolutely no electricity thereby making them perfect insulators.
2. More resistance than Conductors but less than Insulators
As mentioned above, they have properties in-between those of insulators and conductors. One of those is their resistance. They can resist more than conductors but less than insulators.
Problem 1:
Carry out the indicated operations from left to right.
18 divided by (-2/3) * 4 divided by (-7) * (-3) divided by (1/4), but note that anything inside parentheses MUST be done first.
18 div. by (-2/3) could be evaluated by inverting (-2/3) and then multiplying:
18(-3/2) = -27.
Next, multiply this -27 by 4: result is -108.
Divide this result by -7. result: 108/7.
Mult. this result by -3: -324/7
Last, divide this last result by (1/4):
-324
-------
7 -324 4
------------ = --------- * ------ = -1296/7, or -185 1/7
1 7 1
-----
4
