<em>b</em><em> </em>for <em>books</em><em> </em>read. b=1x + 1. the amount of months he's been in the club goes for x and +1 because he already read a book before he joined. if you do easy math, he's been there for 8 months because he read 9 books. i probably got the equation backwards but this works both ways imo.

Answer:
= 10
Step-by-step explanation:
Multiplication first:
(-3 + 8 x 2 - 3) =
(-3 + 16 - 3)
Simplify the rest:
(-3 + 16 - 3)
= (13 - 3)
= 10
 
        
             
        
        
        
13x-6+95=180
Combine like terms
13x=91
Divide by 13
X=7
Two base angles are supplementary/equal 180
