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!

Answer:
opposite sides have the same slope, so it is a parallelogram
Step-by-step explanation:
A parallelogram has opposite sides that are parallel. Here, one pair of opposite sides consists of horizontal lines. Both have zero slope, so are parallel.
The other pair of lines each has a "rise" of 3 units for each "run" of 2 units, so the lines have a slope of 3/2. Both lines have the same slope, so are parallel.
Since opposite sides are parallel, the figure is a parallelogram.
Answer:
Step-by-step explanation:
35 for 9 hours

B agree
A,c, d don’t make sense
See step by step:
<span> 13-2n=19
</span>- 2n = 19 - 13
- 2n = 6
n = -6/2
n = -3
