The expression "5 times the sum of 6 and some number" is written as "30 + 5x" when the unknown number is represented as "x." This expression simplifies by distributing 5 into the sum, resulting in the final form "30 + 5x."
Let's represent the unknown number as "x". The expression "five times the sum of 6 and some number" can be written as "5 * (6 + x)". So, the expression you're looking for is "5 * (6 + x)".
Now, if you want to simplify or solve this expression, you would distribute the 5 into the parentheses:
5 * (6 + x) = 5 * 6 + 5 * x
This simplifies to:
30 + 5x
Therefore, "five times the sum of 6 and some number" is represented by the expression "30 + 5x", where "x" is the unknown number.
