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:
3^x=9^{x+5}
Step-by-step explanation:
3^x=9^{x+5}
x^2-x-6=0
x^4-5x^2+4=0
\sqrt{x-1}-x=-7
\left|3x+1\right|=4
\log _2\left(x+1\right)=\log _3\left(27\right)
3^x=9^{x+5}
If request to solve;
\mathrm{Convert\:}9^{x+5}\mathrm{\:to\:base\:}3
9^{x+5}=\left(3^2\right)^{x+5}
\mathrm{Solve\:}\:x=2\left(x+5\right):\quad x=-10
Answer:
a^2 +a -6
Step-by-step explanation:
(a + 3)(a - 2)
FOIL
first: a*a = a^2
outer: -2*a = -2a
inner: 3*a =3a
Last : -2*3 = -6
Add them together
a^2 -2a+3a -6
Combine like terms
a^2 +a -6
