A retaining wall is being built out of bricks. The bottom row of the wall has 150 bricks. Each row contains 5 fewer bricks than the row below it. How many bricks
should be ordered if the wall is to be 20 rows tall?

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.
