Question

Today Julia practiced her flute for 9 minutes fewer than twice the amount of time she spent

yesterday. If m represents the number of minutes spent practicing yesterday, then the
expression 2m-9 represents how much time she practiced today. JSuppose Julia practiced for
25 minutes yesterday. How many minutes did she spend practicing the flute today?
50 minutes
O 49 minutes
O 41 minutes
O 36 minutes

Answer 1

Julia would have spent 41 minutes.

Explanation:

We know that the equation is 2m - 9, and that m is equal to 25.

So all we have to do is solve.

2m - 9

= 2(25) - 9

= 50 - 9

= 41

So Julia practiced 41 minutes that day.

Hope this helped! :D

Answer 2

The time Julia practiced her flute yesterday is given to us as 25 minutes. In order to find the amount of time Julia practiced today, we will use the expression 2m - 9, where m represents the amount of time she practiced yesterday.

To solve this problem, we need to plug in the value of m (25 minutes) into the given expression so we can obtain the number of minutes she practiced today.

So, we multiply 2 by m (which is 25), so 2 times 25 gives us 50.

The expression then is 50 - 9.

Subtracting 9 from 50, gives us 41.

Therefore, Julia practiced for 41 minutes today. So, the answer is .

Answer: 41 minutes
