Simplify the expression.
5x+6y+ 16
7a)

If n is the amount of sides then there's 38 sides in a polygon with 665 diagonals
7b)
We do the same as 7a) but with 406. We get that
and
. A polygon cant have 30.04 sides
Answer:
A. 
Step-by-step explanation:
E = v + Ir
E - v = Ir (subtract by v on both sides)
(E-v)/I = r (divide by I on both sides)

So he has 4 hrs on his mp3 player...for which jazz makes up 1/6 of it..
so we need 1/6 of 4 hrs...." of " means multiply
1/6 * 4 = 4/6 = 2/3 of an hr <==
