The correct simplification of 8x2(5x 2x2 − 3) is 
<h3>What do you mean by simplification?</h3>
- Simplifying procedures is one way to achieve uniformity in work efforts, expenses, and time. It reduces diversity and variety that is pointless, harmful, or unnecessary.
- Making anything simpler is the act or process of simplification. Everyone is in favor of streamlining court procedures.
- Certain "solving" issues are connected to "simplification" issues. Parentheses and even nested grouping symbols can be found in some equations, just like in some expressions. Whether we're working with equations (so we're also solving) or expressions (and only simplifying), the simplification procedure is the same in both cases.
The correct simplification of 8x2(5x 2x2 − 3).


Rearranging the above expression in descending order of power, we get:
The correct simplification of 8x2(5x 2x2 − 3) is

Answer:
$43.20
Step-by-step explanation:
If each family member buys one ticket and one lunch, then for ticket price t we have the total expenditure as ...
5(t +6.50) = 248.50
t +6.50 = 49.70 . . . . . divide by 5
t = 43.20 . . . . . . . . . . subtract 6.50
The price of each train ticket is $43.20.
