Answer:
The number is 27
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The quotient of 9 and a number added to 30 is 33
30 + (n / 9) = 33
<u>Step 2: Subtract both sides by 30</u>
30 + (n/9) - 30 = 33 - 30
n/9 = 3
<u>Step 3: Multiply both sides by 9</u>
n/9 * 9 = 3 * 9
<em>n = 27</em>
