The tens digit is three less than the units digit. If the digits are reversed, the sum of the reversed number and the original number is 121. Find the original number. help

47, 74

Step-by-step explanation:

Let x = units digit

x – 3 = tens digit

Then the number is 10(x – 3) + x and the reversed number is 10(x) + (x – 3)

Equation

The reversed number plus the original number equal 121.

10(x) + (x – 3) + 10(x – 3) + x = 154

10x + x – 3 + 10x -30 + x = 121

22x – 33 = 121

22x = 154

x = 7 (units digit)

x – 3 = 4 (tens digit)

Answer

The number is (4 X 10) +7 or 47.

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.
