Answer: The number is 5.
Step-by-step explanation:
First, let d be our number.
Since we know that d is our number, we rewrite the expression this way:
3 times d incresed by 15 is 30.
3 times d is 3d; 3d increased by 15 => 3d + 15. This equals 30:
3d + 15 = 30
To solve for d, subtract 15 from both sides:
3d = 15
Next, divide both sides by 3:
d = 5
