Yes that it's correct because numbers that are 5+ round up and numbers that are 4-stay the same.
Answer:
The surface area would be 471.
Lets say the number = x
Six times a number is decreased by 9, the result is 3
6 times x is decreased by 9, the result is 3
(decreased means to subtract and results means equals)
6x - 9 = 3 (add 9 to each side)
<u> +9 +9</u>
6x = 3 + 9
6x = 12 (divide each side by 6)
6x/6 = 12/6
x = 2
The number is 2
