Answer:
Step-by-step explanation:
1 inequality will model the number of hours he spends on the carvings per week and the other inequality will model the amount of money he will spend on materials per week.
He spends 3 hours on type X and 2 hours on type Y, so
3X + 2Y models the hours he spends on each. If he can spend up to 36 hours per week, the inequality sign is less than or equal to. Therefore, the inequality for the number of hours he can spend per week on type X and Y carvings is
3X + 2Y ≤ 36
Now for the money inequality.
He spends $4 for type X carvings and $5 for type Y carvings, so 4X + 5Y models that part of the inequality. If he can spend up to $100 per week, the inequality sign is less than or equal to here as well.
4X + 5Y ≤ 100
Those are the 2 inequalities that make up the system.
Mary, Anne, and Rose decided to race their three pet snails, Anthony, James, and Thomas to see which was fastest. Anthony finished in 23.38 minutes. James finished in 23.65 minutes. Thomas finished in 23.13 minutes. Order the finish times from least amount of time to greatest to see which snail was the winner of this very intense and serious race.
23.12, 23.38, 23.65
