Solve this problem please. Step by Step
8c+5=4c-11

Answers


You said that                               8c + 5  =  4c - 11

Subtract  4c  from each side:      4c + 5  =       - 11

Subtract  5  from each side:        4c        =       - 16

Divide each side by  4 :                c        =        - 4
First you combine like terms: 8c-4c
Your equation now: 4c-5=-11
Next you will add 5 to both sides
Your equation now: 4c = -16
Then you will divided 4 from both side
Your equation now: c=-4
Hope this helps!

What’s the answer to the question

Answers

angle B would be 111° since a pentagon adds up to 540° total.

Answer:

the total angle of a five sided polygon is 540, hence angle a + e + d+ c = 540.

to find b, take 540 - 150 - 92 - 98 - 89 = 111 (the answer)
