Answer:
n = -1
Step-by-step explanation:
Guess your question is to find n
Given:
-6 + 3n = -9
-6 + 3n = -9
Add 6 to both sides
-6 + 6 + 3n = -9 + 6
3n = -3
Divide both sides by 3
n = -3 / 3
= -1
n = -1
Check:
-6 + 3n = -9
-6 + 3(-1) = -9
-6 - 3 = -9
- 9 = - 9
8,748 is the answer because multiple all the number and get 8,748
Answer:
x = 3
Step-by-step explanation:
95 + 85 + 100 + 27x -1 = 360
280 + 27x - 1 = 360
279 + 27x = 360
27x = 81
x = 3
Double check your work:
95 + 85 + 100 + 27(3) - 1 = 360
95 + 85 + 100 + 81 -1 =360
360 = 360

He originally had on his MP 3 player 99 songs
Step-by-step explanation:
The given is:
- George deleted 63 songs from his MP 3 player
- The ratio of songs he deleted to the songs he kept was 7 : 4
We need to find how many songs he originally had on his MP 3 player
Let us solve this problem by using the ratio method
∵ George deleted 63 songs from his MP 3 player
∵ The ratio of songs he deleted to the songs he kept was 7 : 4
→ Deleted : Kept : total
→ 7 : 4 : 11 (7 + 4 = 11)
→ 63 : : x
By using cross multiplication
∵ x × 7 = 63 (11)
∴ 7 x = 693
- Divide both sides by 7
∴ x = 99
∵ x represents the total number of songs
∴ He had 99 songs originally
He originally had on his MP 3 player 99 songs
