x = 126

each ( x - 30 ) equals 96 degrees

Step-by-step explanation:

Since a pentagon's angles all equal 540 degrees, you can set up the equation like so:

x - 30 + x - 30 + x - 30 + x + x=540

Combine like terms:

5x - 90 = 540

Add 90 to each side:

5x = 630

Divide each side by 5:

x = 126

Substitute into the equation to solve:

x - 30

126 - 30

96

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,

mrb

the correct answer to your question is a. 4^4

good luck my friend!

hope this !

maybe if i you could me by giving me brainliest?
