sweet [91]3 years ago
5 0

Answer:

x = 4, y = 9.

Step-by-step explanation:

3x -2y = -6 and y = x+5

Substitute y = x + 5 in the first equation:

3x - 2(x + 5) = -6

3x - 2x - 10 = -6

x = -6 + 10

x = 4

So y = 4 + 5 = 9.

A band expects to put 12 songs on their next CD. The band writes and records 25​% more songs than they expect to put on the CD.
ad-work [718]

Answer: 6 songs will be on the final​ CD.

Step-by-step explanation:

The number of songs that the band expected to put on their next CD is 12.

The band writes and records 25​% more songs than they expect to put on the CD. This means that the additional number of songs that the band recorded is

25/100 × 12 = 0.25 × 12 = 3

Therefore, after writing and recording, the number of song was

12 + 3 = 15

During the editing​ process, 60​% of the songs are removed. It means that the number of songs that were removed is

60/100 × 15 = 0.6 × 15 = 9

Therefore, the number of songs that will be on the final​ CD is

15 - 9 = 6
