Answer:
The greatest number of song he can practice in a week is 2.
Step-by-step explanation:
Suppose, the greatest number of song he can practice in a week is [tex]x[/tex]
He practices each song for [tex]3\frac{1}{2}[/tex] hours. So, the total time required for practicing [tex]x[/tex] number of songs [tex]= (3\frac{1}{2}*x)[/tex] hours.
Given that, he practices his guitar for 9 hours each week.
So, the equation will be......
[tex]3\frac{1}{2}*x= 9\\ \\ x= 9\div 3\frac{1}{2}\\ \\ x=9\div \frac{7}{2}=9 \times \frac{2}{7}=\frac{18}{7}= 2.571.... \approx 2[/tex]
(Rounded as the greatest whole number)
Thus, the greatest number of song he can practice in a week is 2.
Answer:
2 songs.
Step-by-step explanation:
Let x be the number of songs.
We have been given that Sam practices his guitar for 9 hours each week. He practices each song for 3 1/2 hours. So the time taken to practice x songs will be 3.5x.
To find the greatest number of song that Sam can practice we can set an inequality as:
[tex]3.5x\leq 9[/tex]
Let us divide both sides of our inequality by 3.5.
[tex]\frac{3.5x}{3.5}\leq \frac{9}{3.5}[/tex]
[tex]x\leq 2.5714285714285714[/tex]
Therefore, Sam can practice 2 songs in a week.
