Just write 5-8i and then replace the - sign with the + sign: 5+8i.
Make 1 1/5 into improper fraction which is 6/5 and then find the common denominator 6/5 and 5/8.
Common denominator is 40. Multiply 8 by 6 and 8 by 5 so it would become 48/40. Do the same with 5/8 except multiply by 5 which would be 25/40. Subtract 48/40 and 25/40 which is.....
23/40
f(x) = x+.50(x)
where x is the amount the math club raises and
.5x is the amount the principal donates
f(x) is the amount of money for the field trip
we can simplify this to
f(x) = 1.5x by combining like terms
using the original equation
f(150) = 150 + .5(150)
f(150) = 150 +75
f(150) =225
using the simplified equation
f(150) = 1.5(150)
f(150) =225
