Write and solve an equation to find the number: The sum of three times a number and 12 is 45.

Step-by-step explanation:

3x+12=45

3x=45-12

3x=33

3x/3=33/3

x=11

Step-by-step explanation:

Equation

3x +12 = 45                  Subtract 12 from both sides

Solution

3x + 12 - 12 = 45 - 12

3x  = 33                       Divide by 3

3x/3 = 33/3

x = 11

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.
