-9

9 is positive and 18 is negative, so since 18 is negative, you subtract 18 from 9 and get -9.

Answer:

the first one.

Step-by-step explanation:

DJ and decorations are one time flat costs. they are constant. so, together, they are $300.

that is what decreases the profit.

on the other side, $5 per student = 5n in total increases our profit.

so, in total the sum of both (the decreasing amount has a negative sign, if course) :

5n - 300 = 1,500

is the right equation to calculate how many students are needed to make that much profit.

the solution, but the way :

5n - 300 = 1500

5n = 1800

n = 1800/5 = 360 students

For the following equations, find the ratio of a to b. Be sure to show all of your work.
Natalka [10]

Answer:

1.  a/b = 2

2.  a/b = 1/3

Step-by-step explanation:

3a=6b


We want to find a/b

Divide each side by b

3a/b=6b/b

3a/b = 6

Divide each side by 3

3a/3b =6/3

a/b = 2

15a=5b

We want to find a/b

Divide each side by b

15a/b = 5b/b

15a/b = 5

Divide each side by 15

15 a/15b = 5/15

a/b = 1/3
