So there are 4 classes each day, with 6 people per day.
That would be 4*6 people total.
=24
Then there are 30 days, so multiply by 30:
=24*30

=720 people.

So 2/17x=14
Divide each side by 2/17 to get x by itself
This is the same as multiplying by the reciprocal, 17/2
X=17/2*14
X=238/2
So x=119

The scale is 1:12, and the actual car has 16-in wheels.

So the setup would be a proportion:
1 over 12=x over 16
Then cross-multiply
12x=16
Divide by 12
X=16/12
=4/3 or 1 and 1/3 in. wheels on the model car.

5x+14=9
20-3x=-4
-236=29-5g

so:
5x+14=9
-14 -14
5x=-5
/5 /5
x=-1

und:
20-3x=-4
-20 -20
-3x=-24
/-3 /-3
x=8

und:
-236=29-5g
-29 -29
-5g=-265
/-5 /-5
g=53
