What is the simplified value of the expression below? 3(8-4)+2x5.5 a.23 b.31 c.47 d.77

Your equation is 3(8-4)+2*5.5
you want to follow PEMDAS
Parenthesis 
Exponents
Multiplication
Division
Addition
Subtaction

so first you will solve the parenthesis (8-4) = 4
put it into your exquation
3(4)+2*5.5

now the next thing we have is multiplication

3(4) = 12
2*5.5 = 11

now plug it into the equation 

12+11=?

now you just do the addition 

your answer should be 
A. 23

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
