An electrician cuts a 30 ft piece of wire into 2 pieces. One piece is 2ft longer than the other. How long are the pieces?

  piece1:   14 feet

  piece2:  16 feet

Step-by-step explanation:

piece1:   x

piece2:  x + 2

x + x + 2 = 30

2x + 2 = 30

2x = 28

x = 14

piece1:   x = 14

piece2:  x + 2 = 14 + 2 = 16

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.
