Final answer:
To write a simplified expression representing 5 times the sum of X and 3 increased by 10, we start by representing the sum of X and 3 as (X + 3). Then, we multiply this sum by 5 and finally, increase the result by 10.
Step-by-step explanation:
To write a simplified expression representing 5 times the sum of X and 3 increased by 10:
We start by representing the sum of X and 3 as (X + 3).
Then, we multiply this sum by 5 by placing it in parentheses and multiplying it by 5: 5(X + 3).
Finally, we increase this result by 10 by adding 10 outside the parentheses: 5(X + 3) + 10.
So, the simplified expression is 5(X + 3) + 10.
