it is true because 14 is 1/14
In these problems, it is always a good idea to find the total population. In this case, it would be the total number of people who went on the field trip.
28+18+4=50
There are 50 people total.
To find each fraction, just put the number of students/parents/teachers over 50 and simplify.
Students
28/50=14/25
Parents
18/50=9/25
Teachers
4/50=2/25
Hope this helps!
13x+2=11x-1
-13x -13x
2=-2x-1
+1 +1
3=-2x
3/-2=-2/-2x
-1.5=x
10 because here's an example if three people are sharing a pie with 30 pieces everybody gets 10 because 30 pieces of pie divided by three people is 10 :) hope this helps!
1. Joe- 2+b (or 2+1b)
Micheal- 2b
2. Joe- 2+10=12
Micheal- 2x10=20
3. one distributes and the other just adds regularly.
