Answer:

2x+3

Step-by-step explanation:

Since her brother is m years old, you would have to multiply her brother's age by 2 since the question says "...twice here brother's age." This part would equal to the equation 2x. The question also says " ...3 years more..." This would change the equation with the addtion of 3. The completed problem would then be 2x+3. Hope this helped!

How do you solve-

<span>If 75% of the students had taken 8 courses, 25% had not. Of these remaining 25%, 60% of them (or 60% of 25% = 15%) had taken 6 or 7 courses. Thus 90% (75% + 15%) of the students had taken 6, 7 or 8 courses.

Thus only 10% had taken less than 6 courses. I hope this helps.
