Answer:
40, 41, 42
Step-by-step explanation:
x +x+1+x+2=123
3x+3=123
3x=123-3
3x=120
x=120:3
x=40(the first number
40+1=41 (the second number
40+2=42 (the third number
7.6*10^3+2.3*10^5=7600+230000= 237600.

Eric took 20 hours to do the job alone.
<u>Step-by-step explanation</u>:
<u>Given </u>:
- Total work = 75 packages
- Joe took 5 hours to complete the total work.
The amount of work Joe alone can do per hour = 75/5 = 15 packages.
The amount of work Joe and Eric together do per hour = 75/4 = 18.75
The amount of work Eric alone can do per hour = 18.75 - 15 = 3.75
The time Eric took to complete the entire work = 75 / 3.75 = 20 hours.
