A number is divided by 8 and then increased 5, If the result is 20, what is the original number?
- 150
- 120
- 100
- 90
Explanation
The problem states that the number is divided by 8, so we get:x/8
Then, it's increased by 5, so we get:
x/8 + 5
The result is equal to 20, so we set up the equation:
x/8 + 5 = 20
Subtract 5 from both sides:
x/8 = 15
Multiply both sides by 8:
x = 120
So, the original number is 120!
