Since 13.5 divided by 0.75 is 18, there will be no candy left over.
I'm not exactly sure if this is the correct answer.

Answer:
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
Step-by-step explanation:
sin 3x - cos x
This uses Trig Identities.
sin 3x = sin (x + x + x) = sin (x+x)*cos x + cos (x + x) sin x
= 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x)
sin 3x - cos x = 2sinxcosx * cos x + [ (cos x)(cos x) -(sin x)(sin x) ] (sin x) -cos x
sin 3x - cos x = 2sinxcosx * cos x + sinx (cos x)(cos x) -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 sinx cosx * cos x -(sin x)(sin x)(sin x) -cos x
sin 3x - cos x = 3 (sin x)(cos x)(cos x) -(sin x)(sin x)(sin x) -cos x

do you want to know how I got my answer...?
Answer:
Explanation:
Follow PEMDAS in reverse to undo what's happening to x.
We first add 1 to both sides, then divide both sides by 5 to fully isolate x.
Refer to the steps below to see what I mean.
The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.
The solution set for x is anything -3 or larger.
If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
