Question

MJ's friend, Mariella, has 10 less than 2 times as many songs as MJ. If MJ has 'x' songs, how many songs does Mariella have?

a) 2x - 10
b) 2x + 10
c) x - 10
d) x + 10

Answer 1

Mariella has 10 less than 2 times as many songs as MJ. If MJ has 'x' songs, Mariella has 2x - 10 songs, which is answer choice a).

Step-by-step explanation:

The student is asked to express Mariella's number of songs in terms of the variable x, which represents MJ's number of songs. According to the information provided, Mariella has 10 less than 2 times as many songs as MJ has. If MJ has x songs, then 2 times MJ's amount is 2x. Subtracting 10 from this amount gives us Mariella's total number of songs, which can be expressed as 2x - 10. Therefore, the correct answer is a) 2x - 10.
