Answer:

x=3

Step-by-step explanation:

9x+5+2x = 38

Combine like terms

9x+2x   +5 = 38

11x+5 = 38

Subtract 5 from each side

11x+5-5 = 38-5

11x = 33

Divide each side by 11

11x/11 = 33/11

x = 3

Answer:

3(2n + 10) = 54

n = 4

Step-by-step explanation:

3(2n + 10) = 54

Divide both sides by 3

2n + 10 = 18

Subtract 10 form both sides

2n = 8

Divide both sides by 2

n = 4

Select all of the following that are a direct variation.
seropon [69]
Only these are direct variations:

<span>Songs are 99 cents each to download.
Tickets for rides at the fair are $1 each.

Because, for each of them, the total value will be always the product of the number of items times a constant (the unit price).
