Answer: 57%

Step-by-step explanation:

Davis's monthly expenditure and his monthly salary was 3 : 7.

This means that for every $7 he received, he spent $3 out of it.

The amount he saved is therefore:

= 7 - 3

= $4

For every $7 received, he saved $4.

Percent = 4/7

= 57%

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
